Tablets wont eclipse personal computers as fast as once thought, according to studies by market tracker International Data Corporation (IDC). IDC on Friday cut its forecast for shipments of tablets and two-in-one devices combining tablet and laptop features to 233.1 million, saying growth would be about half of what was originally predicted. When we look at the global picture, it would be easy to say that the tablet market is slowing down, said IDC research director for tablets Jean Philippe Bouchard. While shipments in mature markets such as North America and Western Europe were forecast to remain flat, those in emerging regions were expected to climb overall by 12 percent.
