This phone initially looks great, but it is plagued with the same issues that many windows phones have. It has been mentioned before, but I hate all soft buttons, you can;t dial without looking at the phone. And I would hate typing without any tactile feedback. If I wanted all screen, I would have gotten a 8525, I didn't.
The software is revolutionary, and I really like the look of it, but apart from Voicemail trick, my treo does everything already. Maybe not as slick, but I can do it. Threaded SMS, heard that before.
Is a pretty UI worth $600? Maybe, to some. Maybe to me... I'll have to see. BUt Palm has officially been served. Now it is there turn to respond, and the 680/750 isn't gonna be good enough.
