Microsoft currently has around 90% share of the client operating system market with Windows but this will fall to 58% by 2007 as new devices increasingly appear, IDC said. By 2007, Windows on PCs will account for 58% of the client operating system market, with the Symbian OS for communication devices taking 17%, according to IDC figures. Only smart mobile phones with the ability to run applications are considered to have true operating systems, in IDC's definition. Windows for communication devices will account for 6% of the market and Linux for digital video recorders will account for 5%. The server market will also remain mixed, with variants of Unix accounting for 36%, Windows for 35% and Linux for 15%.
