Perhaps you decided to play around with Chromium on a Virtual Machine, and want to keep it on hand to boot up into at any time. Or maybe you just want to try it out easily on different systems… Either way, a 3rd party build of Chromium has made its way to a Thumbdrive near you, thanks to “Hexxeh”.
According to tests, it can fully boot in under 20 seconds (and that includes the long POST that all PC’s still have to deal with) which might make it an excellent solution for quickly booting up and checking emails, etc. Because really, there’s not much else you can do with it at this point…
