Hexxeh, creator of the easiest way to test out Google's Chrome OS, has updated his unofficial ChromiumOS build to automatically update, support more video and Wi-Fi hardware, use webcams and offer menu customisation. All it needs is a 2GB USB stick.
That's all it needs to boot, but whether it sings or just struggles depends on your hardware. It's also a pretty 327 MB download, straight from a server at the moment, but it might be the last time you'll have to download for a while. Automatic updates, which were being beta tested in a previous update, are now set up by default, so you won't have to re-flash your USB drive when Hexxeh pushes another update.
