Hi, Chevy. We noticed you only sell cars made by yourself, Chevrolet, in your dealerships. Well this is unfair to to all the other car manufactures so you're gonna have to display and sell an equal amount of Toyotas, Hondas, Fords, etc.
Not an Android user myself, but all I can say is SO WHAT? There' s no such thing as FREE! If a manufacturer wants to use Android (and it costs you nothing), they best be ready to give something back.
Microsoft did that, too, but they were/are making money out of their OS. Google is giving it for free, making money on search/ads. This will be interesting to follow on, especially for the rationale on whatever they decide.
