Device for Taking Travel Notes?

the Anonymous Wanderer writes "When I go in vacations, I like to take notes and upon return write a travel story for my friends. Until now I've been using a paper notebook, but found that I'm so busy when I come back that the notebook sits for weeks or months unopened. On the other hand, I have some 'dead' time during trips and I'd like to take the notes electronically (final editing could be done upon return). I don't want to carry a laptop or a PDA (too expensive, plus I want to be away from computers at least those 2 weeks per year). Any suggestions for a light, cheap, keyboard-equipped device? Like a travel clock + keyboard and more memory and USB? Thanks, the Anonymous Wanderer."
