Competition is a natural phenomenon in the free market economy. The consumers are provided with wide choices of products and services in the market. There are many players who offer their brands of products and services to the people in every sphere of economic life. Computer, the omnipresent reality in the modern world, along with its various applications are also subjected to this proactive phenomenon.

Take the case of the operating system. Operating System (OS) is the programme that controls the basic functions of a computer. In fact it is the force that makes things work. The graphical user interface (GUI) is an integrated part of the operating system and is considered as the soul of the computer. But for the GUI, the user of the computer may not be able to collect information or make use of the programmes.

It is well known that Microsoft Windows are being used widely in the personal computers. The series of operating systems and graphical user interfaces are actually holding a near monopoly position in the PC market. In the year 2004, market surveys revealed that Microsoft users constitute about 90 per cent of the consuming world, as far as PCs are concerned. There are many versions of Microsoft Windows for computer users to choose from. The trend continued even when the computer enabled mobile phones were introduced in the market. But then Symbian operating system entered the market. They are designed for mobile devices with associated libraries and user interfaces. Jointly promoted by Ericsson, Nokia, Motorola and Psion this innovative operating system targets mobile devices rather than PCs. In the smart phone sector the symbian operating system is reigning supreme, successfully competing with the Microsoft products. In a recent survey it was found that Symbian operating system have market share of 40 per cent in the mobile sector while Microsoft systems have only 13 per cent. Many other competitors are also present in this competitive market. Symbian has many advantages to attract the customers. This operating system enables the users to surf internet without causing hindrance to phone conversations.

Another special feature of the Symbian systems is the adaptability to Global Positioning System (GPS), which has become an integral part of the smart phones. The users have found multiple advantages in this operating system, which is superior to other products in the same category. Reliability, speed and memory management are superb, according to users. Windows based applications require faster CPUs to achieve efficiency equivalent to that of Symbian OS, but then it tends to burden the user with additional expenditures.

But the last word has yet to be told. In a scenario where new technologies are being developed to promote more and more user friendly applications, the companies like Microsoft and Symbian will pursue their efforts to cater the never ending needs of the computer users. The writing on the wall is very clear. Competitions in the market will continue for ever.
