If you like to do a lot of writing, be sure to grab the free Transcriber handwriting recognition software from Microsoft:

I use a heftier version for my handwriting recognition, called Calligrapher. It's just like Transcriber, but includes things like macros and shortcuts. You can get it here:

I also have a folding keyboard for when I need to do a lot of writing. Right now, you can get a GREAT one that folds up very nicely for only $39.99 (They're usually over $100).
What you're buying is a great little device. I've got a lot of the current models to choose from, and I use my 4100 as my primary, everyday Pocket PC.
Good luck. If you've got any more questions, feel free to ask here.
