In a press release IDC said: "Android-based tablets expanded their share of the market notably in 2012, and IDC expects that trend to continue in 2013. Android's (GOOG) share of the market is forecast to reach a peak of 48.8% in 2013 compared to 41.5% in IDC's previous forecast. Android's gains come at the expense of Apple's (AAPL) iOS, which is expected to slip from 51% of the market in 2012 to 46% in 2013. Longer term, both iOS and Android will eventually relinquish some market share to Windows (MSFT)-based tablets, with Windows 8 predicted to grow from 1% of the market in 2012 to 7.4% in 2017. IDC expects Windows RT growth to remain below 3% during the forecast period."
