Windows 8 is slowly gaining market share by taking it from Vista. While there are a lot of critics of Windows 8, the OS isn’t that bad. All new PC’s ship with Windows 8 and it will become more and more prevalent on the desktop scene. But, I am not sure if the increased market share is due to people actually wanting it with their PC, upgrades or custom PC’s, or if it is mainly from people upgrading their older Vista or pre-Vista PC’s with a new model that comes with Windows 8. The numbers don’t really say that much.
