They didn't learn much about the hardware of this phone but claim that you will be able to talk for free with the Google Phone:
The concept is simply, you get a google phone probably even for free or a nominal once time fee and once you run out of credit google asks you to complete some survey or to watch its ads and you get more free minutes. Teenagers are going to love it.
Google didn’t buy double click for nothing and it needs to get that invested money as soon as it can. Now think about it a doubleclick advertising potential and millions if not billions invested in the google adds all available on a phone. Scary even if you are Nokia.
