A hardware analyst with Goldman Sachs, Bill Shope, has lowered his overall forecasts for the tablet industry. In 2011 total unit shipments are now expected to reach just 57.7 million, as compared with an earlier prediction of 60.1 million. For 2012 the estimate shift is slightly smaller, down 2 million units to 78 million. The problem lies with Android tablets, which aren't expected to sell as well, according to Shope.
