I just bought the Compaq iPAQ, Pocket PC. I LOVE it! I usually hate compaq, but this is an exception. It has pocket excel and pocket word. It's also cool because you can transcribe handwritten words for text. The color screen also lights up brighter then any others. Since I use it for work in the dark for the most part, that helps me out extremely.
Any Pocket PC usually will run you upwards to $600-$800. The iPAQ costed me $500.00
Palm Pilots are also cool, but I like the ability to syncronize my Microsoft Outlook.
