Google's Chrome OS came close to being labeled vaporeware after its highly publicized initial announcement, at least by some. But at Google, there was never any doubt about its future. Just as they have done with the Chrome Web browser, Google has poured tons of resources into Chrome OS. It's a radical system, no matter how you slice it. It's the world's first commercially available desktop operating system that relies almost entirely in the cloud. That alone takes a moment to digest.
