Google has officially laid down the ground rules to differentiate between Android and Chrome OS, its two mobile operating systems.
Eric Schmidt, its CEO, told an audience at the Web 2.0 Summit in San Francisco that the soon-to-be-launched Chrome OS would be for keyboards while Android will be limited to touch.
Schmidt didn't confirm whether both operating systems would eventually merge, a possibility that Sergei Brin last year.
This does mean however that Chrome OS won't be used on tablets or on any touch devices from Google and Partners.
But then, Google did use Android OS on Google TV (e.g. the Logitech Revue), whose primary input device is a keyboard.
Schmidt also confirmed that Chrome OS will be officially available in the next few months for Intel and ARM-based devices.
Our own Andy Evans (who sent us some great photos of the Nexus S) was in the audience at the Web 2.0 summit which was organised in association with Federated Media and O'reilly.
