My wife and I have both been playing on Treo 650s since early May. She has over 730 hours on a continuous game; I have been starting new games every couple of days. Niether of us has ever suffered a reset.

One of the major "reset-causers" on the Treo 650 is the VersaMail client. Its database gets corrupted easily - you can read more at the Brighthand forum (http://discussion.brighthand.com)
