A Cheap and Portable Word Processor?

An anonymous reader asks: "Last evening I was waiting for a bus and realized that it would be very nice to have a little portable word processor; not a fancy PDA, but something with a bare minimum of processing power, small screen, and a cheap mini-keyboard, so that it could fit in a jacket pocket. It doesn't seem like an infeasable product - consider the price that all-in-one 8-bit game machines like the C64 DTV go for, add that to the price that the cheap organizers go for, and you get a retail value under $50. The only major difference would be in the software, and with some attention given to expansibility it might even be a decent device for homebrews. Does Slashdot have any thoughts on what might fill these gap, or is there really no product that tries to be small, cheap and low-powered like what I'm looking for?" "When I got home, I did a search for any such devices, and came up with two choices: bulky 1980s machines with outdated connectivity options, found on eBay for pennies - some of these are actually programmable too, interestingly enough; and overpriced 'educational' machines which are almost equivalent to the 80s machines (over $200 or even $300). Electronic organizers are going for under $20, but they are woefully limited machines. The only other cheap option is to get a used PDA."
