I wonder the same thing! When closed, the 9300 looks easier to use as a phone, with regular buttons one can use by touch. The keyboard looks much easier to use for e-mail or notes. Since I've never been able to actually touch one, I don't know, but I hope it might be easy enough to use it for note taking at meetings instead of a laptop...
Of course, Nokia carefully left out the WiFi so they could sell the larger 9500!
I need no camera, and the 9300 sounds perfect enough I've remained with a phone I hate just so I could get any new phone promotions to switch. But, the debut of the 9300 keeps getting put off. The Treo is here NOW. Anyone have any real data to use for a decision?
