I am considering a PDA or pocket PC and would like to get some feedback. Here are the specs I desire in order of importance: 1. Large screen(does not have to be color) 2. Speed 3. Long battery life Wireless would be nice but would have to come at a very slight price increase. Not over $350 but would go up a notch in cost for a substantial increase in performance or if it is the only way to get a full screen size.
