Yesterday Google announced that longtime Android leader Andy Rubin was stepping down as senior vice president of the division. This is big news, since Rubin had been with Android since before the company's 2005 acquisition by Google—he'll be replaced by Sundar Pichai, who, among other things, is also in charge of the Chrome division.

While we don't know much about the circumstances of Rubin's career move—by all appearances, he'll be staying with the company and working on other projects—we couldn't help but wonder what having the Chrome and Android teams under the same person could mean for Google's two operating systems, Android and Chrome OS. Microsoft Editor Peter Bright and I (Associate Writer Andrew Cunningham) both think that some crossover is inevitable, but we don't quite agree on the form it will take.
