Google finally announced the closing of its $12.5 billion acquisition of Motorola, officially marking its entry as a hardware manufacturer. But as CNBC explains here, the Internet behemoth must still figure out what to do with its costly, sprawling new business: It can continue to operate Motorola as it is (and probably continue to bleed money), or it could whittle down operations and focus on just a few key products. Regardless, it now has a chance to wrest more control from carriers, though, which could still be a winning strategy. So as my colleague Kevin C. Tofel writes, competing Android manufacturers like Samsung and HTC should start thinking about building devices for other mobile operating systems.
