Via Scalzi's AOL blog, via another website... A typewriter for sending e-mail. Alas, though this thing apparently worked, it is not a product but an art project for a show. And it's from 2004. Also, it only sends e-mail, not receives it in the version shown.
It apparently was made because someone's mother just wouldn't do e-mail, wouldn't get a computer. A thought which some of the commenters on Gizmondo didn't get. (sigh)
But if it really worked, and in both directions, I know a mother who could use this. (sn*rt)
