Uh, isn't Chrome OS basically just the desktop version of Chrome? How many of the Chrome apps (including desktop Chrome itself) are touch optimized?
Honestly Google needs to just give it up, incorporate desktop Chrome into Android and sell AndroidBooks.
This, there is overlap between their products and android is clearly better and more supported.
Seems like someone high up in google is afraid to kill off chrome OS as if its admitting its a failure. But you can still use the tech developed in making it and incorporate that into making a full chrome browser that runs on android. Like intel killing off their GPU card but using the tech in their cpus.
