Co-founder Andy Rubin says that the key differentiator between Android and Windows Mobile or OS X is "openness." Rather than just an open SDK, the entire operating system is open to inspection,
meaning that the whole mobile industry will have access to the source base. As expected, Google plans to recoup its return on investment by making its ad-supported services available on the mobile
OS. Rubin says there is no "direct-advertising component" in the platform, meaning there will be no special Android-only advertising, just more of the same services Google offers on the Web. Users
can choose whichever Web browser they like.
Rubin contends that Android will not compete with the Apple iPhone. "Apple has a great business in building really, really high-quality consumer products, and the platform that we're building can go into a lot of different products," he said.
