Acer Chairman and Chief Executive Officer J.T. Wang described the controls as “troublesome” during a speech at the Computex trade show in Taipei this week. “They’re really controlling the whole thing, the whole process,” Wang said according to the Bloomberg news agency. Chip suppliers and PC makers “all feel it’s very troublesome,” he added. Wang would not identify the exact restrictions but Microsoft is understood to be creating a controlled experience similar to that of its Windows Phone range of devices.
