Symbian OS is still the “leading figure” in the smartphones market and according to Gartner Symbian’s market share is still the majority with a trend to decline.
Symbian - open source software platform
Nokia’s buying the rest of Symbian that it doesn’t already own, and will then create the Symbian Foundation, in collaboration with a number of other companies, and make Symbian royalty-free and open-source.
Implications to the other OS
The Symbian Foundation stirs up the future of the open mobile platform space. It does seem fair to draw the conclusion that the Symbian Foundation puts the Symbian platform in a stronger position and this will negatively affect the other players.
