I never go anywhere without my PDA. I keep everything in there, including shopping lists, wish lists, a list of my quilt books so I don't buy duplicates; the list goes on and on. The only thing I would recommend that I haven't seen mentioned is that if you're going to invest in a PDA, spend an extra couple of bucks and buy a backup module for it. The Palm OS is pretty stable, but crashes are not unknown, and using the backup module will prevent you from losing any entries you put directly into the PDA, and if it does crash, you can restore your data without synching, if you're away from home at the time.
