I even feel that it will be very tough for Google now to retain its position in the market. Facebook, Twitter, Bing and other such emerging web giants bring innovation and better reach than anyone. 176 million Gmail accounts Vs 400 million facebook users tells that Google is under pressure and need to be innovative. Google need to look beyond search and mircosoft. They should focus more on web products other than giving a fight to software giants.Orkut used to be top social networking website in India but now lost its position to Facebook because Google was busy in Chrome OS. They need to understand that it is very imp to have there own OS but also very imp to understand the need of retaining there grounds.
With the launch of Nokia OVI, i believe google maps will also loose its ground in india. Still in the end i will say that Google is the web Giant and will never let its competitors get any upper edge over him.
