Google pushing a Chrome OS makes me wonder if they have the right confluence of conditions to actually create a system based on the Intel CloneCloud concept, where a netbook OS relies on additional horsepower from a google backed grid cloud that allows expanding an OS beyond a single netbook to including the computing resources of a linked clone in the google cloud. Your personal desktop is semi-anchored between the netbook and a cloud clone instance, a sort of bridged hetereogenous cluster OS. This would also have an easy to exploit subscription service revenue stream, and a semi-controlled user data storage environment that Google can freely mine/index for patterns and metadata. Like Windows lock-in, you become so dependent on google services that the costs to migrate away to either another cloud platform or a standalone OS is excessive.
