Could Google's web-based "Chrome OS" operating system be close to launch? TechCrunch is quoting a "reliable" source who reckons that it could be here within a week.

The operating system will likely be initially rather rickety, due to the demands of creating a whopping great big pile of drivers. It's likely that all but the most common hardware will initially be unsupported. One rumour suggests that Google is creating its own hardware drivers, while another says that the company will leave it to manufacturers to make their devices work.

Google has said that Chrome OS is due to launch "in the Fall", so we're just about within that timescale still. Expect Chrome OS, if it is about to arrive, to be very firmly still a "beta", and not a Microsoft/Apple/Linux destroying monster. Yet.
