I think that your poll is not too fair. I would like to be able to tick the first 3 propositions.
How do I use my N900??
First, as a phone, not a Computer (I do not code any program or things like this) but there are few tools which help me replace my computer when i am on the go for example.
Second, as a multimedia device. I'm satisfied with the 5mp camera and the large storage (even if i only use 25GB (5GB for Apps)- it's quite enough for me) to listen music and store a lot of Photos (I'm very Photomaniac)
At last, for games. There are not a lot of good games like in Android and iOs but i'm a little bit satisfied (preenv and emulators)
But the big thing I love with it , is the ability to tweak it the way you want. For me it's one of the best smartphones I ever had, even if after almost Two years of use, it becomes to be obsolete. If nokia does not want to release another good phone like tghe N900 (N950 would be sweeeeet) I'll for sure move (And create another farewell post) to android (Galaxy Note and Nexus are very tempting) or to the iPhone 5 (I wait for the OS and the iPhone to be mature enough)
That's it.
