Batteries and backups

Note to self: remember to charge the batteries more often and to do backups of my Clié more regularly. It's the second time I've lost evertyhing and had to go back to a very old backup. If I miss an appointment, at least you'll know why...
Better yet but a bit more expensive: change the rescue battery in the Clié, if it exists (Clié T615, I'll have to look it up).
