I would never buy anything from apple, they lock their devices down in a way that makes me feel physically sick. I will probably never use Android for similar reasons. Also, I'm a GNU/Linux guy, stopped using Windows over a decade ago, I want a proper Linux box in my pocket.

When I replace my n900 it will be with another OPEN phone, if there isn't one available I will get the dumbest phone I can find and it will act as a modem for a seperate mobile computing device. My n900 is probably my main computer these days and it's really nice having a single device to fulfill all my mobile tech needs, convergence is important, but not as important as freedom.
