The Zire 21 would be a nice enough unit but my buddy suffered data loss on it too many times. Skip that one and go for the Zire 31 if you must 'aim low'.

There are infrared keyboards out there for the keyboard duty.

-> Beware that you will not be making an exactly ready to print document. In fact, I would forgo Documents to go and simply try the notepad for the words and then sync it to the PC, copy/paste the words into Word and format it there.

I've seen some Treo 90's out on the refurb market and Radio Shack for 99 bucks. That model has a mini keypad and is a model I own as well as my buddy. The SD memory card is nice since you can transfer content to flash so battery outages don't wipe out your work.

-> In closing, a PDA is no substitute for a PC/Mac.
