I had some spare time this weekend, so I booted up Hexxah's build of Chromium OS to see what it's like. I used VirtualBox, and it was too laggy to do much with, but it looks like it would perform well enough on a real computer. Here's the link to Hexxah's website: http://chromeos.hexxeh.net/ Let me know if there's anything specific you'd like to see.
