Android is necessary as-is for what it is.
But I think you've almost hit it on the nose with the rest. This OS/platform is the underlying architecture for a Google branded wave platform on which most (if not all) of their software applications will eventually reside. But Wave is available now, without Google's 'OS' and is a generic real time data sharing platform. Google OS is (near as I can tell) a business solution for those that want Google's tools and complete control of their data in-house.
They go together like PB & J but they are distinct.
