I just converted from Palm to Pocket PC. Only been a week so far but I am beginning to like the Pocket PC better. I was using a Palm for almost 4 years, the latest being the m505. There are some programs I still haven't found suitable replacements for yet, but I know in time I will find them. My main concern tough is the battery life, although when I think back it ws a rare occasion that I didn't top off the batteries daily since I ususally put the PDA in the hotsync cradle/charger overnight anyway.
Just my two cents
