I use mine all the time. I used to have a big Franklin planner, but I'm much happier with my little Palm. Mr RedRose got me a Tungsten for my birthday, so now I'm REALLY happy!
One of the most useful things on my palm is an awesome program called Vindigo. It's basically a restaurant guide, entertainment guide, and map program for nearly all major US (and many international) cities. I can't tell you how often I use it! I'll never forget the time we were in London, standing in the middle of Leicester Square, wondering where to eat. Out came my Palm, and within minutes we found just the type of restaurant we were looking for. It's about $25 a year, and you can get it
here.
PS - No, I do not work for Vindigo.
