I have a 650. I've played around w/ the 700 and I'm convinced that the 700 is better. More memory, 1.3 mp cam/video, easier to send video messaging, etc..... The 650 is good, but the 700p is superior. My opinion on thte 700w isn't that great since I've had two Windows smartphones in the past (Q and SDA), but to each their own.
