I've been looking at these devices for a while. I primarily want my phone for pictures, navigation (with internal maps [no data]), and phone calls. I have been burned on two N900's although there is a listing for one that claims it is in its sealed factory box. I like the idea of the n900 although I'm not sure I would ever use it to close to its full capability.

It seems all of these devices can do what I want and do them well but is there a reason I should pick one device over the other? I'm not terribly informed when it comes to phones.
