An anonymous reader writes "Pundits continue to weigh in on Steve Sinofsky's sudden exit from Microsoft (as executive head of Windows Division, he oversaw the development and release of Windows 7 and 8). SemiAccurate's Charlie Demerjian sees Microsoft headed for a steep decline, with their habit of creating walled gardens deliberately incompatible with competitors' platforms finally catching up to them. Few PC users are upgrading to Windows 8 with its unwanted Touch UI, sales of the Surface tablet are disappointing, and few are buying Windows Phones. On the Sinofsky front, Microsoft watcher Mary Jo Foley is willing to take the Redmond insiders' word that the departure was more about Sinofsky's communication style and deficiencies as a team player than on unfavorable market prospects for Windows 8 and Surface. Meanwhile, anonymous blogger Mini-Microsoft had suspiciously little to say."
