Mac OS X has slowly crept up in popularity since its release, never making huge jumps but rather steadily pushing skyward. To Apple's delight, Mac OS X gains come at the decline of Windows, and recently OS X has seen a 5% growth since last month. That increase puts it at just over 8% overall, a significant number when you consider the sheer amount of desktops in the world. These gains seem to come directly from Microsoft losses. Could Windows market share slip below 90% for the first time in many years?

That's certainly a possibility, with Windows estimated to be around 90.29% - quite a drop from a year ago, even more of a drop from three years ago.
