I thought the same thing and bought the 700. Bluetooth is a lot better in the 700 but it ended up being more of a pain than what it was worth. On the 650 most things, like speed dials, were very easy. With the Windows OS5 on the 700 it seems to take many more steps to get what you want and there were just as many, if not more, hangups and resets. I ended up going back to my 650 in spite of bad BT.
