Forget Chromebooks: Chrome OS is Coming to Windows.
Google has announced a bevy of stand alone apps that will run outside of Chrome, and will bring a Launcher app to Windows. In effect, you will be running Chrome OS apps on your Windows desktop. If you haven't brought your Start button back with Start8 or another third party app, Google wants to replace it with Chrome Launcher, which will give you one button access to all sorts of Google apps. While the apps will run outside the browser, they will sync with the cloud, and the new term of the day is "packaged apps". These apps will run even if you don't have an Internet connection, and will sync up when you do connect. Chrome OS won't replace Windows right away, of course, but you will certainly be using it.
