SuperSite for Windows posted a preview on Google Chrome OS
A quote from the article:
>> Google Chrome OS Preview
Thursday's on campus announcement was the second major event Google held for its nascent Chrome OS, and while some have churlishly referred to the project as vaporware, let's not be silly: Chrome OS is real, and by just announcing that it's working on such a thing, Google has already changed the PC operating landscape and then some. The question, going forward, is how much more it will change things. I anticipate seeing Microsoft lower the pricing on its functionally-challenged Windows 7 Starter edition, for example. But if the software giant is serious about competing with Google, it will need to do the unthinkable and simply make Windows 7 Starter available to PC makers for free. It will go kicking and screaming into such a future. The only question is how long it takes.
