"it has replaced my paper notebook for my police duty notebook" -- I am impressed that it stands up to daily use like that.
My brother's new cellphone is a Handspring, I don't know what model.
I bought a TRGPro from a forumite. It's a Palm IIIxe clone. Another forumite had a 128 MB CompactFlash that fit it, so I've got a good bit of storage space

I know it's yesterday's news as far as all the upgrades everyone's made since, but I only paid $104 for the whole setup.
What I like best, though, isn't the PDA itself, it's the Palm Desktop that came on CD for my computer. This is a nice management tool, especially the calendar and phone book.
Although I am a !!! MASTER OF GRAFFITI !!! I still like being able to Copy and Paste from my other data sources and then Hotsync into the PDA to carry the data around.
I envy you guys going to school now. We used slide rules for math and sci classes. The first, simple, four-banger pocket calculators didn't come out till I was out of the Air Force -- where I used to do flight calculations on a circular slide rule!
PDAs were undreamed of ...
