The Transmeta processors are really, really #@@#$ slow. You don't need much for Office tasks, though.
I recall some Fujitsu barebones on eBay for about 60$. They were short a few parts, and you'd need to add a battery, hard drive, and RAM, but once you did, you'd have an ultraportable laptop with a touchscreen to boot.
(I'm currently bidding one one myself.)
