Mashable.com have "screenshots" of the upcoming Google Chrome OS. It's an early developer beta but it looks... basic, too basic. They might be a very early set of screenshots but they still looks a bit too Windows 95. If fact it looks a little like a college project which makes me think it's a fake. That said a simple OS like that would probably work well on the target market of underpowered netbooks but they will have a long long way to go before Google OS becomes a mainstream OS of choice for most users.
