It’s been four months since Google dropped a bombshell with its announcement that it is getting into the PC operating system game, in a direct challenge to Microsoft and Apple.

Now the world may get the first glimpse of Chrome OS, the PC operating system as envisioned by the folks in Mountain View, California.

According to a report in TechCrunch citing “a reliable source,” a version of the Chrome operating system will be available for public download within a week.

TechCrunch said Google has a legion of engineers working on hardware driver support, and notes that the software may only run on a limited set of PCs at first:

We expect Google will be careful with messaging around the launch, and endorse a small set of devices for installation. EEE PC netbooks, for example, may be one set of devices that Google will say are ready to use Chrome OS. There will likely be others as well, but don’t expect to be able to install it on whatever laptop or desktop machine you have from day one.
