The document provides an overview of various mobile operating systems including Symbian OS, BlackBerry OS, Windows Mobile, iPhone OS, and Android. It discusses their key features and differences. Symbian OS powers most smartphones globally but has limited reach in the US. BlackBerry OS leads the US market but has less global reach than Symbian. Windows Mobile also has a large user base but its next version is late to market. iPhone OS has driven strong growth with its app store ecosystem but apps are restricted to Apple's approval process. Android is new but open source which could accelerate innovation, though demand currently trails iPhone.
