I got a keyboard for my Palm IIIc from my husband a few Christmases ago. I used it quite a lot for a few months. Even used it to take a travelogue when we went on vacation.

But then I got a laptop, and I used that more. I still carry around the Palm and the keyboard in my purse, but I don't use it as much as I used to.

However it is VERY much more portable than a laptop. And you can also get programs like Documents-to-Go, as you mentioned, to transfer files between Palm and computer. I have used the Palm for some notes for my novel in the past.

But it's all in habits.
