i feel both have their advantages and disadvantages but I love both of them!
N900: browsing,watching YouTube in browser!! Fm transmitter (still confuses my mates),multimedia,keyboard
N9:brilliant phone, brilliant display, more RAM, better battery life

looking around the thread showed me that N900 is still a winner!!!

WOW!

Can you (OP) please add a poll in the thread?

N900 wins, deal with it :P

I don't. This is still by far the best smartphone I've ever used, it just feels like something is lacking compared to the N800. A large part of that is just in hardware. I like the larger screen, better speakers, and direction pad on the front of the device. I like that the kickstand goes all the way across the back and that you can slide your hand through it to hold it. The shorter stylus seems easier to use.

On the software side things are less clear. The basic UI and functionality seems to work better "out of the box" in Diablo, but I do keep finding ways to customize the software in N900 to get it closer to how I'd like...which I certainly haven't been able to do with something like Android.

btw...quick side question. Is there a keyboard shortcut to bring up the application menu? I seem to have poor luck at hitting the menu in the upper left portion of the screen on the first try.

I had an N810.

The N900 is so much faster it's not even funny : )

I feel the same.

The N9 I've had two months just feels like a phone, albeit one of the nicest phones I've ever used, but there's no real wow factor like the N900 had in terms of hacking and modding.

Same with me. I used an N9 for a few months after it was first released, but I went back to my N900 for good last month and haven't looked back.

The N9 is a beautifully designed device that "just works" as a phone. But using the N9 has also helped me come to realize that the majority of my time using a mobile is not actually spent on the phone. Thus, despite all of it's quirks (and some embarrassing letdowns in business situations), I still get more everyday utility from the N900 then I did with the N9.

That's just my opinion based on my use case. Like I said, the N9 is a beautiful and powerful device, I just didn't get as much out of it as I do with the N900.

after all of this i wont buy an N9/50 :-D maybe just another N900 or an Android one !

Or a BB10 device ^

*if it turns out to be as good as it seems.

Or, more likely for me, a JollaMobile device. But, for now, the N900 is tops.

Edit:
Besides the already mentioned things that make the N900 better, such as the removable battery, removable storage, FM Transmitter, etc, I have to include the IR port. It is nice to be able to use the N900 as the remote shutter trigger for my K5 camera.
