Predictions from Gartner analyst Carolina Milanesi, a research vice president and the market analysis firm, will startle long-time computer users: essentially, Microsoft's long reign at the top of the technological heap is over. The company predicts devices using Apple's iOS and OS X will outsell devices running the various forms of Windows (including mobile) by 2015 -- even including business and enterprise sales that have traditionally been a stronghold for the Redmond giant. However, it will be Google -- not Apple -- taking the crown from Microsoft.
