I realized after that last question, I should have made my Palm answer a review, sorry for the duplicates - If you need a PDA, Palm makes great ones!
Check out www.palm.com for product comparisons.
If you're unsure which type to get, being that there are so many different ones these days, consider the fact that there is more software and applications out there for the Palm Operating System than any other one. So, if you're big into downloading games, applications, diet and excercise programs, etc, you'll have a lot more variety with the Palm OS than any other.
Newer models have WiFi and Bluetooth built in which is a lot more convenient than having to remember a card to plug into your PDA for internet access.
They also now have their own software built in that syncs to Outlook, eliminating the need for Chapura.
A GREAT buy!
