Google announced they will start a new project, Chrome OS. Chrome OS is open source and run in x86 and ARM CPU. That is different from Android. That is targeted at a small netbook market.

Well, that makes me to remember gOS. gOS is a linux distro which is a kind of Google Apps Enabled Linux and some netbooks are using that as OS too. Whether Chrome OS like gOS to use Linux?!
