Microsoft's mobile operating system is able to increase its spread slowly to forecast the market researchers at the U.S. Institute. In 2012, the system will take about ten percent market share. Thus, it would still significantly behind Apple and RIM. The cooperation with Nokia will however make 2015 the breakthrough. However, Microsoft will achieve in this period by no means a similar distribution, as it has done that Nokia's own Symbian in 2010. Nokia Symbian itself is not followed, so Gartner calculates that the operating system will disappear by 2015 almost entirely from the market.

Apple lost market share in
How many market research firm Gartner is also assumed that the market share of Apple in the coming years will move only between 15 and 20 percent. The highlight of the distribution will reach Apple even this year. Then shall the company in the world this year alone sell almost 91 million units.

New players unlikely
Gartner considered in the forecast, only the shares of the new devices sold. It can therefore be assumed that the real distribution of market shares by existing older units of this forecast is different. The market researchers do not believe that coming years a new player on the market will come in the. Comparable results Comscore delivered last for the U.S. market, which is also dominated by Android now. In Germany, however, still dominate the market Apple devices.
