Chrome OS isn't competing with Windows or Linux, in the same way the iPhone OS isn't competing with Windows. They are for two different types of device, bought by different markets for different reasons. Chrome OS and iPhone are both about operating systems for small, portable, constrained devices. Chrome OS will power miniature web browsers, while Windows and distros like Ubuntu will power full-fat machines for real work. Basically, Chrome won't be a mini-Windows or a mini-Ubuntu, but a maxi-Android.
