I finished reading Vol 05 of Make last night, and discovered that there's a company selling Poqet PCs. I had one of those, back in the day. After the Atari Portfolio and before the Newton. Make 05, Published February 2006, lists the price as $30. If you click thru the link above, you'll see they're now selling them for $160.
For $30, I'd've bought a couple of 'em. For $160, it's not worth it.
