Microsoft's Surface RT tablet sold 1 million units in the fourth quarter, fewer than expected, according to a UBS analyst. The analyst, Brent Thill, had expected 2 million Surface RT tablets to sell. In a note to investors, he said that customers are preferring iPads over Surface tablets.
Part of Microsoft's problem is that the software maker sold the Surface RT only in its own stores through much of the fourth quarter, he said, and didn't add other stores
, including Best Buy and Staples, until mid-December.
