Maybe bigger device == wear spread across more blocks, but isn't this offset by more blocks == higher probability of some going bad? Either way, I'd prefer to keep things that cause lots of erase/write cycles out of the soldered-on chip.

Anyway, if this was a real problem, we'd be flooded with N810 users with dead internal cards by now
Oh, I'm not worried about it dying while still in warranty (all N810s are still < 2 years old).

Compared to ReiserFS & XFS, which is irrelevant here. Compared to ext2 it should use slightly more power because of the journal (otherwise they're the same fs).

USB-OTG devices are required to have a micro-AB socket (a square one without the bevelled corners). If it doesn't take micro-A plugs, then either it doesn't support host mode, or it doesn't comply to standards, or wikipedia is wrong. http://en.wikipedia.org/wiki/Univers...-AB_Socket_OTG
The N900 doesn't support USB host mode and the limitation comes at hardware level. Igor Stoppa and myself provide more details at http://lists.maemo.org/pipermail/mae...er/020830.html

WHAT?

Does that mean it's impossible to use any USB periphery with the n900 - not even with power injection?

All previous NITs had this feature. USB support missing on the n900 would be a huge letdown.

Isnt the issue that it cant provide power for the USB device. What about independently powered drives which dont rely on the USB host to power. I may have misread the issue.

Holy S**t, please don't tell me I can't attach a self powered external HD (or ANY other self powered USB device) to the N900, it was really something I was looking to...
reading the link posted by qgil I didn't get if the problem is with the power of the device of incompatibility between USB hardware and the USB consortium rules... in this last case, wouldn't there have been the same problems with the previous internet tablets??

or is the "support" word being used as "officially supported" by Nokia, not providing the Host mode out of the box?


One totally different thing:
the N900 has a IR port; I have a Nokia 6630 since some years, and I *never* felt the need in a IR port having it bluetooth; what should I use a IR port for? anybody can illustrate me some uses for this? thanks in advance.
(hey, not complaining for a extra feature in this case, just curious )

USB consortium has strict rules for many aspects, including connectors. AFAIK, the previous tablets don't suffer this problem because they don't charge through USB port and, although they don't support USB host mode out of the box, a patch is available through the community.

Ah so the reason why it wouldn't support USB host mode is because you can now charge the n900 over USB..

Bah, that's an awful tradeoff if so. I want both (it's useful being able to plug my flash drives into my n800).

Now this is one thing I am dissapointed to hear.

Lack of MMS, smaller screen etc were ok and not something I would quibble over.
But lack of any USB Host mode seems like a real loss to me.
If its going to be my mobile computer, I would definitely need USB host so as to attach portable media (HDD) to it etc.

I thougt GA said he was sure USB Host mode would be supported via the host cable or something ... but Quim seems to lay to rest such an idea.

My endless optimism is endlessly punished by Nokia.
