Google CEO Larry Page in a second day of testimony at trial made the unusual remark that he was "not sure" if Android was a critical asset for Google. While it was "very important," he emphasized the company's sometimes understated view that Android was ultimately a vehicle for Google services like ads, not an end into itself. The mobile OS was developed partly in response to earlier Java devices, he said: even with 100 phones to try, none of them would use Google's services properly.
