It may not exactly be a huge surprise given the recent market share numbers, but Google CEO Eric Schmidt has recently confirmed that Android is, in fact, profitable for the company. Of course, it doesn't make all that money from Android directly, but Schmidt says that Android-based phones are already generating enough advertising revenue to cover the cost of development. What's more, while he doesn't provide any current specific numbers, Schmidt did say that he expects there to someday be one billion Android phones in the world, and that if each one generated just $10 per user per year it would be a $10 billion business -- or, as Newsweek notes, about half of Google's total revenue for this year. That's just a tidbit from the full Newsweek piece, though -- hit up the source link below to read the whole thing, which also includes a bit of perspective from Google's Andy Rubin.
