Google's buyout of Motorola is not just about patents but echoing the Apple-like integrated hardware model Google swore it would never follow, a major leak alleged on Wednesday. Although patent security is a key goal, one aim is now said to be to design hardware, not just to build the OS. The company's mobile VP Andy Rubin, who the WSJ said was personally involved in brokering the Motorola deal, may have helped push for a merger with this in mind.
