Major flaw, otherwise immensely useful

The bad: Every time I have to change the batteries (which I have learned to do in about 5 seconds) the data in the unit is lost. So you need to pay close attention to your battery level, and sync the data before you swap batteries. Sync frequently! Don't leave it in your cold car! Also, the screen is small for my eyes.

The Good: Great interface (Palm OS), connecting to AvantGo.com to get loads of news, content with every sync. Great way to keep all indespensible info, reminders, etc.. on your person at all times. Sturdy, comfortable unit. excellent compromise of size and functionality.
