From the kernel diff and defconfig there's a BCM2048 (Bt + FM/RDS receiver).

Can someone confirm this?

Actually, could we see the dmesg output and list of modules?

* Video recording file format: .mp4; codec: MPEG-4

That's more vague than I'd like. I'd be nice to know if it records in Simple or Advanced Simple. Part 10 seems highly unlikely, and they'd probably call that one out a bit more directly were it used.

There are a few hardware points obviously missing from the specs, so, no jumping to conclusions just yet :) (for example, then don't list anything about the front-panel light/proximity sensors, of if the video section applies to the main camera or the user-facing cam). I don't really expect any more from Skype and Adobe than then did the last time around. That 9.4 flash version might be an achilles heel for web usage considering some sites already go for v10 :(

skatebiker

Nice, but why a smaller screen than the N810 ?? I'd expect a larger one (e.g. Archos 5).
And no more Wayfinder Maps ? That is way better than Nokia Maps.

Sure it does. If it is a device you want MOST people to always take them which is usually their mobile PHONE, it has to be smaller.

The Cortex A8 says it has "the ability to scale in speed from 600MHz to greater than 1GHz".

To your ear ? There is a headset included so holding it to your ear is not necessary. When one holds a phone to one's ear use a regular phone weighing far less than 180 g. And the N810 sized device does fit into a pocket.
The main reason for the 3G added too it is IMHO that for mobile internet no more bluetooth is needed to an external phone.

The n810 weights 226 g, and I don't want to carry a headset all the time anyway.
And 180g is not that much considering that there have been 200gr or heavier phones on the market. But there hasn't been a 5" phone, that'd be just silly.
A 5" tablet is OK, but not a phone.

I don't really see the point of putting up outdated versions when flash sites are notorious for oversensitive version checking. I understand Adobe probably doesn't have an ARM compatible Flash 10, I'm just afraid that we'll get updates with the same frequency as we did on the N810, and Flash is one those components we (as in both OSS developers and Nokia) can't really change.

Bear in mind this is only the first Maemo 5 device. There are almost certainly more on the way next year which would probably have different specs for different market segments.

Nokia's never done just one smartphone a year, they've always released about 5 high end models per year (plus about 30 cheaper models but those will be Symbian).

Their release rate on the tablets was low because the tablets didn't sell as well as the phones, but now that Maemo is on phones the extra sales should justify a higher release rate.


To your ear ? There is a headset included so holding it to your ear is not necessary. When one holds a phone to one's ear use a regular phone weighing far less than 180 g. And the N810 sized device does fit into a pocket.
The main reason for the 3G added too it is IMHO that for mobile internet no more bluetooth is needed to an external phone.

Most people who buy smart devices buy smartphones, so the primary function is clearly phone calls. If you mess with the phone call side of things, the whole show is over.

Nokia has had their fingers burned over this in the past, they're never going to mess with how phonecalls work again. They cancelled the Nokia 7700 (http://www.gsmarena.com/nokia_7700-570.php) before it was even released apparently because reviewers hated its N-gage-style sidetalking, and had to retool it as the 7710 with "normal" talking before they dared put it on shop shelves.

I'm confused by the headset - the specs say a WH-205 which looks like a nice small set with soft earbuds.

http://europe.nokia.com/MEDIA_BANK_100/R6Accessories/W/WH-205/R6_WH-205_240x240.png

But the photo in the specs shows shows a headset that is much more scary.

I never liked my n800 headset and always carry a set of headphones for music only.

Do I understand correctly that it has only 256Mb RAM ? That's only double than N810 which is almost 3 years older.
How much can you achieve with 256Mb when you have a full Firefox browser.
I'm very afraid the history is going to repeat itself (N770, G1 Android, etc): we're going to ran out of RAM and next version will have more RAM out of the factory.
Why can't they put 1Gb RAM from start ?! It's not that expensive.

Though, I usually put my N810 in my jeans and my cell phone in my phone pocket in the jacket. The extra mms on the N900 might just make a difference on that, tho'.

I'm confused about the 3G data connectivity. First of all, the n900 doesn't have any frequency that is relevant to me in Canada, but does " Maximum speed PS 384/384 kbps (DL/UL) HSPA 900/1700/2100" seem really slow to anyone else? My E71 technically connects to Rogers' 7.2Mbps network and I typically get 1-2Mbps in speed tests. 384kbps is a big step backwards...

Interesting. Documents2Go is a great app on Palm platforms I've used in the past.

Presumably this will be a paid-for app. Although if so it seems a little bit odd mentioning it as part of the specs of the N900, as that should presumably cover out-of-the-box functionality.

The mobile space doesn't move the way the desktop space does.

Maemo Browser has been heavily optimized for mobile use. You'll be able to get plenty of use out of that 256MB of RAM and 768MB of swap.

Don't think in terms of desktop RAM, mobile RAM is much more expensive both in terms of power usage and price. In fact, nobody even make a 1GB PoP to go on the OMAP3.

Even with relatively simple internal editor it would be great to download photos from camera, tag and only later import into full blown photo management system on desktop (or send directly to flickr).

It was just a few days ago, it says EMS was "made obsolete" by MMS...

Nother thing is, as a developer, I don't think the system has to be all that smart. You set up a button saying "write message" instead of "write sms". On the "write message" page, there's an option to insert an image. If that button is clicked, the you send the message as an MMS, if not, as a SMS.


Aaaah, too exiting, I have to go home now or my hungry female will make me deadened.

Only devices that offer compatible multimedia message or e-mail features can receive and display multimedia messages. Content appearance may vary. Some images and ring tones can not be forwarded

( the N900 is here and due to be released finally)

I really really wish i had waited to get this now instead of getting my n810, I plan on either giving it away or selling it and getting the N900.
Can anybody give some good advice to a young gadget lover thats just a bit over taken by the videos and pic's of the N900. I just would like another opinion on whether its a good idea to buy it or wait, when its really every thing i wished the n810 was out of the box. the one thing that is holding me back is the fact that its gona pretty much be tied to T-moble which i'm not sure i will go to when i get back to the states...

is it something i could use wit out utilizing the phone feature, meaning could i get away with just using the wifi feature to basically use it like i do my current n810?

any feed back would be great, thanks

i am tempted to say that if nokia plays up google voice support during nokia world, they are going to score a major media win vs apple ;)

As far as I can see they don't include GV support themselves, so the only thing that they can say is that they have an open development platform so if anyone wants to write a GV app, no one's gonna stop them. And probably mention that there's already such a community app - DialCentral ;)

Linking to those European sites, makes me lol. People here are complaining about 550 Euros for this device, when the n97 retails for 650 Euros and there are dumb feature phones for 850 and 1300. 550 is such a great price for the N900 in comparison.

I didn't see anything in the specs that might indicate if this will have native support for external input devices. It's got USB OTG & BT and I assume a keyboard will work, but will mouse support be better than on the NXX series?

With the TV out & the good mouse support, this could easily replace a laptop.

On that thought, since this is charged using the micro usb port, can you charge it and use OTG devices at the same time? (i.e. charge and use a usb mouse or keyboard or flash drive). I would love to use the tv out and the usb to hook this up to an after market LCD touchscreen for 7" on incar delight! After all, Nokia says this thing doesnt really "need' the harware keyboard with Maemo 5.

So yeah Charge plus OTG usb devices? Yes or no?

USB Host?

Even with relatively simple internal editor it would be great to download photos from camera, tag and only later import into full blown photo management system on desktop (or send directly to flickr).

Also - I really want to see digiKam on this :)

Also2 - I wonder if with declared openness will be some day possible to access RAW files from Nokia camera.

There is an app USBHost which probably works on the N900 and otherwise when you have an SD with MicroSD in it on your camera you can easily plug it into the Micro SD slot as with the N810.

That's more vague than I'd like. I'd be nice to know if it records in Simple or Advanced Simple. Part 10 seems highly unlikely, and they'd probably call that one out a bit more directly were it used.

No codecs for Ogg Vorbis and Ogg Theora. But I would have been very surprised if Nokia shipped with those codecs.

Isn't this all GStreamer (http://gstreamer.freedesktop.org/documentation/plugins.html)? Ogg and Theora should be included in the base codecs package. As for sjgadsby's questions, I'm curious too... But it seems to me that recording in other formats with community-written software shouldn't be too difficult.

FLAC support and 32GB might be enough to make me buy this. If this costs $199 on contract, I can see Nokia moving a LOT of hardware.

Edit: Also, yesterday, Google put up like a million ebooks for free in EPUB format. Hopefully FBReader will be available. That said, reading books on the n800 is a painful experience. Literally, it hurts to have to push the tiny button over and over to turn the page, and the touch screen just plain doesn't work properly for page turning. It's the little things like this that make me hesitate, because it all seems so nice in theory.

I have a quick question.

I live in the US and have a AT&T connection. I had a Nokia 6102i initially with them, with the data plan.

I ordered a e71 through Amazon.com (unlocked, obviously). I then inserted the SIM card from the 6102i to the e71, and everything worked. The data rate is 3.5G where I live, and is absolutely awesome.

Now, can I order this n900, and if I just remove the SIM from my e71 and insert it into my n900, will it continue to work? Same speed?

(The thing is, I am not a fan of buying subsidized cheaper phones from carriers. I would rather get some toy from them, buy a costly unlocked phone straight from vendor and insert the SIM in there. This way I can use the same handset in other countries)

spock
08-27-2009, 04:15 PM
I don't think the n900 has the same 3G frequency as AT&T uses, so it'll work as a GSM phone and using EDGE for data but no 3G. This also excludes ALL of Canada since there's only one GSM provider here at the moment.

It should work, that is after all the entire point of SIM cards, so that users can swap phones whenever they want.

If you lived here in Europe I could guarantee 100% that it would work. I do it all the time, I have one SIM card between half a dozen phones and never have any problems.

Unfortunately the sometimes rather awful people who operate phone networks in North America seem to put in all kinds of dirty tricks to try and absolutely control everything their users do.

Hmmm. Delicious. I have a question....I couldn't find the answer so I figured maybe one of you mavens knew. What is the maximum resolution supported by the n900's external display option? I'm thinking along the lines of if I connected it to a computer monitor and a keyboard.... I seem to remember a certain noBounds project (http://www.internettablettalk.com/2008/03/14/the-nobounds-project/) that seemed to be implemented on a n810. From what I can see the CA-75U connects via the 3.5mm jack (huh?) and terminates in component video (please tell me if this isn't true).

Somewhere in the deluge of info, there was also mention of the other method of viewing was UPnP via WLAN. Any ideas what the resolution limit would be in that case? I've seen somewhere (http://www.tomshardware.com/news/ti-omap3,4316.html) that OMAP3 supports 720p HD video, but I don't know what implementation that was vs what implementation is in the n900.

Just don't put a sim card in it and you'll have only wi-fi like on the n810.

At brick and mortar, definitely. I don't think I've ever found a SIM-free in a physical store.

The only truly free mobile market is in countries where phone locking is banned. It's shocking that any country allows it.

Is there any possible advantage to a customer having their phone locked? Does it promote competition in any possible way? Nope. All it does is reduce competition and make phone networks lazy.

Some people seem to think "free market" means an economy where companies can do whatever they want. In fact a real free market means an economy where customers can do whatever they want, choose whichever services they want, which means the companies have to jump to it if they want to keep people coming back for more. The harder you make companies work for customers, the more efficient and innovative they will be.

Honestly, I don't know.

When I try to view (most) Flash objects (myspace music player, various video sites) on my N810, they all say I need to upgrade to the latest version of flash (which is ver10 atm), which is not possible.

Are you absolutely sure you haven't got Flash switched off some of the time? If you go to a Flash site on the tablets with Flash switched off, you'll get exactly the same error message about it being out of date even when it isn't.

Flash automatically switches off if the tablet runs out of RAM, and it won't tell you it's switched off so you won't know it has.

08-27-2009, 05:15 PM

No problem. The words are too similar, and it gets worse when you have to read spec sheets from different video hardware manufacturers who randomly pick one or the other to abbreviate as "CV".

...there was also mention of the other method of viewing was UPnP via WLAN. Any ideas what the resolution limit would be in that case?

I'm guessing, but that's likely a less "hard" boundary. It's probably going to depend upon the processor load vs capability, the bus, and the connection. It's an area that will be ripe for exploration and experimentation once the device ships.

[QUOTE=JayOnThaBeat;316623]Honestly, I don't know.

Then that makes two of us.... ;-)

Nokia has licensed sourcecode for Adobe Flash Player, and I don't have full details on the implementation... hard for me to talk specific details yet, sorry.

But I do know that many content sites check for H.264 support, which arrived on the desktop in Adobe Flash Player 9.0.115.0 in December of last year. Some sites today specifically use Player 10 features, and some always check for the current versions as a security nudge... it's hard to generalize about sites' various detection schemes.

But, as before, we're in the final months of an architecture change... Player 10 is moving beyond laptops to mobile and home systems. First results should be at the end of the year, with production ramping up next year. This generation features over-the-air updating, as well as intrinsic cross-device support, so things should be simpler than they are today.

Best word on what the N900 can do would come from Nokia themselves, but I know that general progress is being made in this area, if that's of help.

The first time I took an iPhone it stroke me how thin it is. It felt alien in my hand and i didn't like it. I think that 18mm is pretty normal thickness for a phone to feel good in my grip. My current phone is thicker, so it's an improvement for me ;) I guess it's a matter of taste, but I really think one should try it out in person before deciding.

Compass + accelerometer = Augmented reality w/ low CPU\bandwidth usage

Otherwise you'll have to process the movement from the video feed or something.

I'm also very disappointed about the lack of a digital compass, and I suppose for someone very enterprising it should be possible to add a bluetooth dongle... smart bluetooth chip acting as serial device + microcontroller or PLD + ADC + analog compass should do it. Pre digitized compass is too expensive I think.

Does anyone know why the N900 lacks 802.11n?

This seems to be a strange omission. :confused:

Not all that strange. I doubt the N900 can saturate an 802.11g link in any real-world task, and it certainly doesn't have room for multiple antennas for MIMO. The only real benefit would be the ability to operate on 2.4GHz n-only networks, but those are practically non-existent anyway.



So, did anyone catch this detail in the specs from forum.nokia.com:
Supported Document Formats
Excel, PDF, Powerpoint, Word[1]
Notes
1 Document format support via installable application (Dataviz).
Where DataViz is the shop that makes Documents To Go for basically every platform except Maemo 4. I hadn't heard any mention of this yet (although maybe I just overlooked?), but it looks like great news for business-type users.

And the dongle is affixed somewhere on the device? That'd be neat, but kind of annoying that it:
- costs extra
- is optional to the device (when profiling your audience)
- needs separate power

I have no idea of how much AR apps would really matter in the realworld without a headgear-type setup. I think it'd be awkward to take out your smartphone and aim it around and around when you need to use it ;) BUT.. rumor is, Apple is going to make this 'a feature' in their next OS increment. So I'm expecting the community here to ***** about how apple didn't invent AR but profit from hyping it up and taking up all the limelight (and secretly envy Apple for doing so).

Yes, for some reason Apple is holding back all AR related apps. Yelp got through because they hid the AR feature as an easter egg (you engage it by shaking the phone 3 times).

I don't know about the compass being unfaithful, maybe it should drink less.

Please forgive me if it's been discussed already in this (lengthy) thread, but can anyone tell me what the Proximity Sensor might be (and might be for)? It's listed alongside the "3D Accelerometer" in "Additional features", so presumably it's not related to Bluetooth proximity detection. Or camera auto-focus. Or is it?

I believe is so that if you aren't around the tablet, it dims or turns off the screen.

@ralphb: the proximity sensor on iphone is located near the earphone slot just above the screen. It detects nearby objects (1-5cm from the screen?) and afaik it's ONLY used to detect if the user is holding up the phone to their ear\face. If they are, then the screen (and touchscreen) is immediately turned off to avoid unintentional input from your face and saves power.

I believe it's used similarly here (I saw some sensor 'holes' around the N900's earphone opening, one of them could be it).

It's OTG, so, of course.
I posted a question in the wiki about power for extended host-mode sessions, and the answer from Jaffa included a statement that Nokia does not support host mode.

Do you have any further info on OTG operation?

EDIT: My apologies to Jaffa, who was using the term "support" more precisely than many other contributors to these forums. It often seems to mean merely that two things can cohabit without actually blowing each other up.

qole has found that answering "Of course" doesn't quite cover the subject. See his post at http://talk.maemo.org/showpost.php?p=320585&postcount=88

Just had 10 minutes to play with a N900 in the Nokia Store, Helsinki.

I wish I could have had more time but there were people waiting behind me and my wife's continuous "can we go now" was starting to bring me out of my trance :(

Overall very, very impressed and I will not be cancelling my pre-order :) Switching between desktops, applications and the dashboard is smooth as silk and very intuitive. The build quality is good and the screen is responsive and very sharp. The UI graphics are also pretty sweet and with the user customisation potential I think we can safely say that Nokia have taken it to the next level - chew on that Apple1:p

The only problems I noticed were:

1. YouTube videos did not stream well over wifi - JKK posted a very good video which also shows the same problem

http://www.umpcportal.com/2009/09/jkk-gets-hands-on-with-the-nokia-n900-video-and-podcast/

2. There is some v-sync tearing visible now and then - scrolling through the panoramic desktops and playing back a video I shot with the device

3. Whilst zooming in and out during browsing the phone had problems keeping up with the rendering.

4. Activating links in the browser was a little tricky - but I think that most of that was me not being used to the touchscreen - I also didn't have time to play with the "mouse cursor" thingy

All of the above should be fixable in firmware updates. I do not know if there will be a firmware upgrade before the production models ship (probably) but my feeling is that the N900 will need a couple of decent firmware upgrades before it really starts to fly.

Also, the device could have been better set up as a demo model. For example there were no video clips, photos or music library pre-installed - which is pretty poor given the its capabilities in those areas.

In my opinion, Nokia firmware/application development and support and community application development are the factors that will make the difference between this being a very good or a truly great device. Let there be no doubt (I know there's not much here :)) the N900 and Maemo have enormous potential.

Roll on October :cool:

I tried out the N900 as well.

1. Did not notice vsync tearing, even though I used to want 85+ Hz CRT screens, minimum. Maybe I was lucky and didn't trigger it. The worst I did was load a large site in the background while panning the desktop.

2. Panning the desktop jerks a bit, but it doesn't look like a performance problem. More like it's swapping too aggressively and can't load the next screen fast enough. FPS seemed completely smooth.

3. Had some trouble with the touchscreen, probably because I like my 5800 so much. The 5800 screen is just so insensitive you can rest your finger on it and just so sensitive touching it with your nail triggers an action. The N900 was so sensitive I think my presses were registering in between my nail and thumb, which my fingers didn't expect. I guess more sensitivity is better, but I hope it doesn't strain my thumb more.

4. Mouse cursor needs optimization. I had trouble triggering it before I realized it only activated at the bottom of the left side, not the whole left side. Even then it was hit and miss at first, until I got used to it.

5. Was unable to use the scrollbar at least in the browser. This is bad. I don't want to kinetic scroll through meters of text and playlists, even though it's obviously better for gradual scrolling. I wonder if there's already a bug filed about this.

6. Demo people need more training. They didn't even remember how to activate the main menu or ask me if I want to preorder (already have).

7. Tried xterm. Don't care about fourth row of keys, but it REALLY badly needs another column of keys labeled / TAB -, so please, please fix this in the next devices. (Esc and | behind shift on the same keys too)

8. Seems pretty awesome overall, but you should ship a 5-10 line UI guide with it if you don't want idiots ranting about how much easier the iPhone is.


Edit: although really I shouldn't complain about the salespeople. In some other country they would've tried to forcibly sell me god knows what and I would've left the store after ten seconds of use. They were very professional and left me alone with the N900.

Thanks for the hands on experience report. It might be nice to have a Maemo members N900 hands on thread to collect and collate experiences from now (pre commercial shipments) to Christmas (too much noise already!). I have a feeling that the Nokia Maemo team might be looking here for feedback and inspiration ;)

I will try to do my bit when I get my own N900 and with a bit of organisation we can collectively deliver feedback that has more validity and greater focus.

Any more N900 first experiences out there...?

Correction accepted. I have edited my post accordingly, including apologies for misconstruing your answer.

I still think that power supply in host mode is a serious question. The usbLAN app by jolouis should have given Maemo a chance to grow out of the toyshop and find a market replacing some of the laptops and notebooks that travellers haul in their hand baggage. Connection to hotel-room data ports is a requirement for that market. So is a full-size keyboard (which can go in checked baggage), and many business users avoid bluetooth for security reasons. USB sticks are absolutely standard tools these days. It is not always possible to schedule a full battery when these things are needed.

TV out is "PAL and NTSC".

Does this mean it can give either, or will we have different models in different markets?

World travellers are every sensitive to these things.

If you go into 'TV out' Settings, you get to choose either PAL or NTSC.

So, I'd say you get both.

There's a dev link (?) somewhere where it is explicitly stated that MMS was not included for initial release and listed a series of rationalizations for it. So, most definitely "no" to MMS at release.

Roll on October :cool:

I went to see the N900 on Saturday. The Nokia rep that was handling the device at the time didn't really know anything about it (I knew more). I think it may be because they haven't yet recieved training on it?

I asked her if it was a pre-prod or a prototype. She said it was a prototype with about a month old software loaded (NOT the latest version & NOT the version at NW AFAIK). She also said the hardware wasn't final and that the touch screen in this device had already begun to loose its sensitivity when I tried it on Saturday (they received the device on the 3rd of sept). I wonder if they now have a device from NW or several devices? You'd think it would be better for the compan to show of a newer device with a touchscreen that is not a prototype.

tl;dr version:

My experience with the device was awesome. I tried playing youtube videos (clicked on the first one I could on the main page) and it loaded and played without problems or stuttering as seen in some videos, I wonder if the device was booted before the poster I quoted tried the divce? The rep said that over 200 people try this prototype every day, and since it's an early software it might suffer from memory leaks which would deteriorate video playback smoothness. The device froze just before I tested it and the rep booted it just prior to handing it to me. Flash seems to take around 10 seconds to load after the main page has loaded, the cursor that you load from the left side worked just fine once I got to used it, as did the spin zooming with one hand, to get better performance out of it you need to spin in a small circle, not a wide one.

I loved the stylus + web browsing. That combined with the Highres screen made web browsing awesome. It limited the need to zoom in to click links like you have to do on the iPhone (if they are closely spaced). It loaded heavy sites like engadget or hs.fi easily, beating IE 6 on the PC.

The screen was IMO just as sensitive as on the iPhone, eventhough it wasn't as good as it was suposed to be.

I like it, will be definately buying it.

If you feel I missed something, ask. I could go back and test it again later in the week, since my school & work place are quite close to the flagship store.

Oh yeah, they should reveale availability this week, and the rep told me to expect it in the first half of october, possibly the first week.

And 5800 (or other Symbian phone) isn't an accurate indicator of what the N900 can do.

This is a big step forward - integrating linux with 3G, so I think it's prudent to watch reviews and videos to ensure that certain functionality or use cases do in fact work.

well the umts data should be a radio thing, as the gsm radio used the same channel for both talk and data.

still, nokia's mms explanation makes about zero sense, given that android seems to handle it fine, without a need for kernel patches.

all in all, there should be no technical hitch, in theory, when it comes to surfing and talking at the same time.

Just because simultaneous data and voice is supported by UMTS doesn't mean that the N900 supports it. MMS is a case in point. It is supported by UMTS and yet there is some hitch, technical or not, which prevents the N900 from performing MMS.

Point is, we can't assume that the N900 supports a particular feature just because the feature is part of the UMTS standard.

Presumably yes (unless someone finally produces a realistic unionfs for Linux and makes it available as a module on Maemo).

But that isn't so bad, icons and desktop file in /usr/share and application code, images, translations in /opt/application.

This is all conjecture though, as Nokia haven't announced yet how they intend developers to use /opt (although it's being left a little late!)

The word "support" in the question was not the word the questioner was looking for - it's too vague and has too many meanings in IT.

Yep, the word "support" is probably the most misused word in tech support, in my experience. Even the people who use it frequently don't understand what they are saying.

What it usually means is, "hey, you may be able to do that, and more power to you if you do, but we aren't going out of our way to help you and we take no responsibility for how well you do it."

People misinterpret it thus: "well, you don't support it, so you obviously oppose it," like we were talking some sort of political process. It doesn't mean that. Often, technicians themselves use this line of reasoning to chase away people who are trying to do something, like "we told you we don't support that, and if you are having problems now, it's your own fault" as if people trying to do it are somehow immoral.

Users who do something that isn't supported are perfectly free to do so, but they can't expect help from a company that has announced that it won't help. That is all that "we don't support that" means.

Yes, I should have seen this /opt thing coming when kimitake said he's using /opt/qt4 to hold the Qt libs... Was hoping for some unionfs action, myself, too. Duh. Back to my Qt-on-loop-device monstrosity, it looks like we might be needing it for Fremantle, too :) :(

Thanks.

A posibility to format 32G internal memory on ext2/ext3 ?

I don't see why you couldn't format it ext2/3..though you would lose the ability to use the N900 as a mass storage device on windows machines.

It's not that easy, or better to say not without consequences on Diablo, where certain bits expected to have a VFAT partition on /media/mmc2. We'll see if the N900 inherits that stance or not :)

I talked to timeless about this one and the assumptions are a lot more limited in Fremantle than they were in Diablo. So, no, ext3 shouldn't be an issue.

Im guessing the usb is host, so can i just plug in a usb key and it will show up as mass storage?

Join the club. I too guessed that any normal computer user reading the specs, with references to USB mass storage etc., would interpret them as you have. I got flamed by the big man. Apparently Nokia's customers are not supposed to be interested in host mode, even if the device is billed as a "computer", for Nokia's first time ever.

You need to read the earlier part of this thread and the discussion about what "support" means.

You should also read the long threads about host mode on earlier Maemo devices. It eventually turned out to be very easy to switch USB modes, once you got some basic facts that Nokia wasn't handing out. For a long time, Nokia's line was that you needed to have a Linux PC handy if you wanted to switch modes.

For the N900, as for the earlier devices, the default USB mode is to act as a peripheral device, connected to your PC for transferring files back and forth.

It is generally believed that the Maemo community will be able to figure out how to change modes on the new device, as it did for the earlier ones. Watch this forum for the next few months.

as per qoles earlier post....

OK bad news, using the standard micro USB cable, my always-useful Female-Female adapter, and an 8GB USB key, I installed and ran "usbcontrol" from the repositories and the mode wouldn't switch from "b_idle" to "host" at all. Trying the old "echo host > /sys/.../musb_hdrc/mode" had the same result. Whatever you write, it is overwritten with "b_idle"...

Is this just because he did not have a powered adapter. I havent seen anyone that said host mode was working with and OTG adaptor.....

USB OTG isn't powered, pin 5 is simply grounded which tells the software that it needs to be in host mode. jolouis manufactures these (http://www.electronicproductonline.com/catalog/product_info.php?products_id=1781) adaptors for the N800.

I'm confused about the 3G data connectivity. First of all, the n900 doesn't have any frequency that is relevant to me in Canada, but does " Maximum speed PS 384/384 kbps (DL/UL) HSPA 900/1700/2100" seem really slow to anyone else? My E71 technically connects to Rogers' 7.2Mbps network and I typically get 1-2Mbps in speed tests. 384kbps is a big step backwards...

Oh spock it is relevant, Wind Mobile, which should be launching in October (crosses fingers) uses that band for 3g. Screw Rogers.

Presumably yes (unless someone finally produces a realistic unionfs for Linux and makes it available as a module on Maemo).

But that isn't so bad, icons and desktop file in /usr/share and application code, images, translations in /opt/application.

This is all conjecture though, as Nokia haven't announced yet how they intend developers to use /opt (although it's being left a little late!)

Well, it's official now. For better or worse, it's 1GB of /opt ext3 to shove everything into (http://talk.maemo.org/showthread.php?t=31435).

Will the N900 support an upgrade to Maemo 6?

That question has been asked multiple times.

The answer is that there's no official answer yet. It is too early for Nokia to commit to anything. However, expectations are that Maemo 6 devices will bring a smaller processing power jump than is occuring between OS2008 devices and Maemo 5 devices. Therefore, it appears probable that Maemo 6 will work on Maemo 5 devices.

If not, there's always Mer, which will be developing alongside Harmattan.

Buy (or not) based up on what the N900 will give you now though, not what might happen in a year or so.

The plug I linked to on ebay has a micro type B plug on one end and a type A receptacle on the other to plug in normal USB devices (mouse, keyboard, USB sticks, hubs, etc...). The plug is an OTG adapter so it will switch the N810 into host mode. The plug you linked to from Amazon are just gender benders - male to female. It will not put the device into hose mode and a software switch solution would be necessary.

Injection is necessary regardless of cable used if your device requires more power than the device can deliver. The NXXX do not provide enough power to power some USB sticks, harddrives, etc... so you'll need to provide the power. If the device is in host mode you could use a powered hub.

Using is what I meant with normal use. Idle use is keeping it in your pocket.

Ive just been hanging out at the onedotzero exhibition in Londons Southbank and i managed to score some alone time with the N900.

....I will post some more thoughts when i get back to my desktop.
.

I spent about 20mins with the device and overall i was impressed, any doubts i had about owning the N900 are now long gone.

I started playing with Karsten's 3D text app which projected messages on to the side of a building which showed off the accelerometer as i moved around text sucked up from Facebook,Twitter and others streaming across a 100ft+ wall. I felt like a Borg taking in the worlds thoughts.

Hardware wise it feels solid and natural in the hand, the keyboard was immediately usable and the learning curve was working out where all the usual keys are and adjusting to the offset spacebar, after 10mins i was flowing nicely. The thing that slowed me down was shifting for 1+2 because theres only one shift key on the left, it was annoying to try and press two keys so close to each other. So a left and right shift key here would be ideal.

The sreen felt solid and there was no sense of give or squishiness, responsiveness was fine in most cases, moving widgets around the home screen was instant and the only part that reminded me of M4, the rest is all new. At times the home screen and photo app wouldnt respond well to short swipes, you need to use a confident and firm swipe to activate it but if you use your nail it was very sensitive, maybe thats by design, maybe screen tech, but i remember what Quim said about the sensitivity being dialled down by design. The rest of the UI responded well to short swipes.

I had a chance to go through the process of setting up new widgets, email, photos and have a look around the repo, it felt like home, easy to use and the UI flowed nicely, I dont think ive ever picked up a new UI so quickly.

I plugged in my quality headphones and jammed while exploring the device, the audio didnt hesitate while doing other stuff and the quality was on par with other N-Series but didnt have time to fully pass judgement. The 2 videos i played worked and looked nice without any obvious judder or smearing but again hard to judge without using my own sources.

The only thing i didnt get to play with sadly was the browser due to lack of connectivity but kinetic scrolling in the repo was sa-weeet. :D

I know people are saying its not a NIT any more and its just a smartphone but when you use it, you really feel like your using a device that is more than a smartphone and im really excited about getting my N900.

Big thanks to Karsten for being so accommodating. :)

The fact, that the homescreen isn't in portrait mode doesn't mean, that the n900 don't support portrait mode. Every developer can make their programs to support portrait mode, even based on the accelerometer. And as we've discussed many times before, Nokia will add MMS functionality with a OS-update.

For sure, on a device like this, whats the point of MMS? People who don't have email on their phone don't deserve to receive multimedia! lol

just wish it could show up on older maemo, or even somehow on mer.

Well we know how to talk to bme, it's on the wiki, so creating a Energy Meter for N8x0 is doable for someone with spare time. Me, I don't have enough spare time and just fake it by parsing ftd logs, which is user-unfriendly to say the least, and fills up the rootfs until everything crawls to a halt :)

And as we've discussed many times before, Nokia will add MMS functionality with a OS-update.

Uh, they will? Where did you get that information from because I have not seen any Nokian saying anything like that.

Does N900 support Java Midlets OTB?since this is just about the only thing which is stopping me from a preorder.

Thanks in advance.

No. No midlets of any kind.

Is the accelerometer official? It isn't mentioned in Nokia's N900 technical specifications (http://maemo.nokia.com/n900/specifications/). So, I'm wondering...

This page does not mention an accelerometer, and I can't watch the video on either my laptop or on my N810.

Ah, well...my intention was to show you the demonstration of the bounce game..which dramatically shows off the accelerometer in action. There are other videos that show the switch from portrait to landscape as you change the orientation of the handset...but they aren't as cool ;)

Short version: yes there is an accelerometer.

what do you think :D? look at all the videos

OK, I suppose that the GPS isn't accurate enough and that the cameras aren't used, so that this means that there is an accelerometer. :) I'm still wondering why Nokia doesn't say a word about it in their spec.

I've seen such a video, but isn't it something that could also be done with a gyroscope?

gyroscope? um, yeah..in theory I suppose if you want to waste money. A solid state gyroscope would be at least as much as the n900 by itself...assuming you could find one small enough. And the gyroscope definitely wouldn't help out in the bounce game with the linear movements that move the ball into the air.

edit: mems single-axis gyroscopes have come down signficantly in price since i last looked....they are now $50-ish. Still doesn't help with linear motion though and they would need to be calibrated occasionally unlike an accelerometer which does not.

gyroscope? .

I heard some people on a tech podcast refer to the iPhone's accelerometer as a gyroscope. Plenty other phones have these too, so.......
I'm running out of research time. Can anyone authoritatively explain what exactly is a smartphone accelerometer and how does it work?
