By the end of 2010 analysts are forecasting that the Android OS will be the second best selling operating system in the world.

Gartner has forecast that Android will take over 17.7 % of the OS market while Symbian in first place has over 40%. Android is closely followed by BlackBerry which has 17.5% and Apple's iOS is in fourth place with 15.4% of the market.

The worldwide mobile operating system (OS) market will be dominated by Symbian and Android, as the two OSs will account for 59.8 percent of mobile OS sales by 2014

The worldwide mobile OS market is dominated by four players: Symbian , Android, Research In Motion and iOS," said Roberta Cozza, principal research analyst at Gartner. "Launches of updated operating systems - such as Apple iOS 4, BlackBerry OS 6, Symbian 3 and Symbian 4, and Windows Phone 7 - will help maintain strong growth in smartphones in 2H10 and 2011 and spur innovation. However, we believe that market share in the OS space will consolidate around a few key OS providers that have the most support from CSPs and developers and strong brand awareness with consumer and enterprise customers."
