Google was full of surprises in 2012. It outdid Apple easily in mobile OS features. It rolled out a whole line of Nexus Android devices that are undeniably top notch. And it launched the Knowledge Graph, a watershed moment between the keyword-searching past of the Web and a future Web that understands whole concepts. 2012 was also the year that Google unified its offerings under a single privacy policy, a move that freaked out lots of people, but which was totally rational from Google's perspective.
