Check out PDACentral for lots of info and links for all sorts of PDAs. Palm I have had a Pilot since they were first released. The Pilot is the standard by which all current generation PDAs should be judged. The UI was designed for small, low resolution, monochrome displays. As a result, it doesn't have a lot of junk.
Most operations are quick and easy.
The Pilot is also fun to hack on. As a result, there are a lot of freeware and shareware applications. These days there are a number of other decent ways to store information encrypted. Dinky Pad - more doodling and making small drawings. I love having all my info, but I really miss my Pilot.
