G. Pascal Zachary wrote a great article on why Google wants to have an operating system of its own now. It has an interesting analysis of how Microsoft dominates the OS world too. The risks of building a new operating system is too high. Many efforts were made in the past to unseat Microsoft but each of them failed. Like me everyone is looking at Google to find out what it does. It also is not immune to failure when it comes to operating system. Undoubtedly Microsoft is too much successful in this arena and not only Google has to produce something technologically superb but also cloud computing has to become as successful as people are predicting it to be.
