Microsoft Surface Tablet Sales: 3 Million Sold in Q1?

Is it possible that Microsoft (NASDAQ: MSFT) shipped 3 million Surface tablets worldwide in Q1 2013? Microsoft isn’t saying word one about it, not even in its fiscal Q3 2013 earnings report that showed Windows division revenue rose 23 percent to $5.7 billion. But, according to Boston-based researcher Strategy Analytics in a new tablet OS market share report, Microsoft can claim a 7.5 percent share of the 40.6 million tablet units shipped globally in Q1 2013.
