I hope most of us have worked or have information of the machines/desktops where we used to have multiple OS installed. For example: multiple versions of windows or both windows and linux Operating systems on one single machine or hardware. As per the rule in electorinics that the processing power doubles every three year and the hardware size reduced to half. Using the same concept and with today's new technology can we have multiple OS in single computing device(Ipad/Tablets/Mobiles) I was thinking is there a way where we can have the multiple mobile operating systems like Android, Symbian, Windows etc one one single mobile.

If that can be possible then one mobile can serve all the purposes. Ifd Nokia Develop any such technology then Nokia can be a market leader once again globally. If anybody have anything to add in this, you are most welcome.
