I currently have the Treo 650. It sucks. It drops calls, it loses phone #s that i know i put in there, and the key board is way too small. I will be getting the 8700c. Heres a idea for anyone in a contract with Cingular and that doesnt want to pay full price. Add a new line for $10 and you get the 2 year deal. You dont save any in the long run but you dont have to pay retail upfront. Hope i helped someone
