Gartner, one of the top research and analysis companies in the world, has run the numbers and decided that Android could very well hold the #1 spot by 2014. Nokia's Symbian OS is likely to hold the top spot until 2014, and the analysts aren't certain Android will have taken the lead by then:
Symbian will remain at the top of Gartner's worldwide OS ranking due to Nokia's volume and the push into more mass market price points. However, by the end of the forecast period, the No. 1 spot will be contested with Android, which will be at a very similar share level.
