This was Google's strategy, too, with the launch of Android. But Google was in an entirely different position; it entered the market early, just after the iPhone, and Google's services, like Maps, Docs, Gmail, and Contacts, already were your defaults. They didn't have to convince anyone to use Gmail as their primary email service on a phone. Everyone already wanted to use Gmail on a phone. So Google says, hey, use our great services which you already use! And then Google gets lots of data about you in return.
