i beleive that google are taking over the world so to speak and in 10 years google will be dominating the os market amounst other things, my reasoning is that they are slowing introducing more and more software and with the release of chrome os more and more developers will get on board and more and more programs or apps will be made compatible for there os, then once compatibilty has reached a high they will be able to release an os for desktops/laptops that is very compatible and from a trusted brand,
google is obviously aware of its stage on the world market and many people (who may be very computer illiterate) have now heard someone moaning about microsoft, google will take advantage of this and your average person will be swayed towards a google os knowing it as a trusted brand they have used for years, is very simple and fun to use and very popular for example my mum uses google for everything never even types in a web address.
slowly introducing chrome os, although a very limited os, will allow time for apps/software to become fully compatible before any release of a major os,
only chrome os is causing a stir a people are curious and excited and they already have major comp manufacturers on board ( i think dell is)
