Itty-bitty, teeny-weeny Linux PCs (DesktopLinux)

Not mentioned in the article is the Linutop:

According to the Linutop development wiki and the LinuxBIOS home page, the Linutop ships with 
LinuxBIOS.  That, combined with its out-of-the-box support for booting off a USB flash drive
(the 
Linutop has no internal storage), it should boot really quickly.

I'm considering getting one of these for an embedded project; anyone have experience with
them?
