Apple was the lead mobile PC vendor in the fourth quarter of 2011 and the rest of the year, at least when including tablets, an NPD DisplaySearch report shows. The company shipped just under 23.4 million MacBooks and iPads in the fourth quarter, and more than 62.8 million for the entire year. NPD observes, though, that almost 80 percent of Apple's numbers were iPads, estimated at 18.7 million in Q4, and 48.4 million for the whole year.
