Hi Guys, Im planning to switch my brand new condition Treo 650 for a new Treo 680. What are my main advantages or disadvantages that i might face over switching over. Is there any handy feature i would miss from the 650 or does it inly get better ? Ofcourse to start with it has double the RAM. Then i found that it has the nifty feature to respond with sms text instead of just cutting a call. What else please ? Any of you who have taken this jump and experienced both fones please let me know. Thanks a lot.
