Want the latest and greatest that Chromium OS has to offer? Weren't one of the lucky ones to receive a Google Chrome Notebook? Vanilla is for you! Each day at around 6PM GMT the latest code is downloaded automatically and compiled into images you can try out, containing the latest changes. You can get images in either USB, VirtualBox or VMWare format. For the best experience, it's recommended you use the USB images. If these don't boot on your device then go ahead and try the VirtualBox or VMWare image. These should always work (assuming the build wasn't broken at the time they were built), but you'll find they're quite slow, because there's no graphical acceleration.
