I agree with nilchak, but I've got to say I am starting to come around to the idea of something with a reasonable screen size (i.e. the 3.5") and being more pocketable, and being programmable.

So yeah, the applications will be more phone-esque, I can't see myself watching feature films or poring over many spreadsheets, but I can think of some cool apps that would use the location + always connected abilities of GSM (and hopefully a better GPS too!)
