Gizmodo article all about this Gentoo Linux-based mini PC (including screenshots).
"There's a cheap computer on the way that undercuts them all, the $99 Zonbu, due this summer in a silent-running form factor that's about the size of a paperback book. It has 4GB of flash memory on board, and automatically backs up a copy of your data online. Besides that $99 purchase price, you'll also pay $12.95 a month (for 25GB,scales up to 100GB for more money) to store its data on the Zonbu servers, giving you the ability to compute anywhere with this tiny device, or access your data from other PCs. If you don't commit to a service plan, the little PC costs $250."
I'm sure that somebody will break it from the confines of its subscription service.
