believed to have only sold 1.7 million Surface tablets since launch

Steve Ballmer sounded pretty confident when his company debuted the Surface tablet last fall. At one point, he even said “I don’t think anybody has done a product that is the product that I see customers wanting,” implying that had.But I think by now, it’s pretty clr that’s not the case. Not only did the software giant have tot $900 millionin unsold Surfaces last quarter, but estimates based on a new SEC filing suggest that it’s only sold 1.7 million of them since launch…GeekWirepoints to’s 10Kthat it just filed with theSecurities and Exchange Commission, which discloses that the company only made $853 million from its Surface lineup. The filing is annual, so it dates back to the tablet’s introduction.“The company doesn’t disclose the of units sold, and the range of products from the Surface RT to the Surface Pro makes it difficult to derive an average selling price.But hypothetically, if the average price were $500 (the original price of the base-level Surface RT), the revenue figure suggests that total units sold were in the range of 1.7 million units as of the end of June.”The site’s 1.7 million approximation is in line with areport from Bloombergback in March, which estimated that had sold 1.5 million units up to that point. For reference, sold14 million iPadslast quarter, or about 1.2M per week.And the company knows there’s a problem. Following a major fire sale, Ballmer hosted a closed-door town hall meeting last week where hereportedly admittedthey’d built “a few more” Surfaces than they could sell. He also said a new one is in the works.
