Yeah I know that there exists an article somewhere with the same heading. But in my view thats not the future of google. If google had aspirations to get into O.S. market they would have started doing stuff oriented towads the same. But all google tries to do is to do with browser...they hire guys from mozilla, they get a search utility going which has a browser based interface and what not. All this clearly shows that GooOS may remian a fiction for ever.
From where I see it, the future of google seems to be much more inclined towards web applications than OS. What I see coming from google in coming years is an integration of Gmail, Orkut(which as of now is not google product as such), picassa etc into one complete utility where you once log in you may do usual mail stuff, it remembers your settings and serves news to you as you want it, it shows all your friends and you may do the addictive scrapping stuff, also the normal search thing which may also be customized according to your taste and ofcourse you may blog also from the same utility.
So much for integrated utility. What more google may offer? Google Office or GOffice is the next thing that comes to my mind.Google may start a service creating a killer app where you can create a document like word (imagine writing a project report with that powerful google search, with prefecthing on, on every word, definitions, spell check, conversions, stock quotes, trivia, encyclopedia, exact distance between two places and a satellite map of the same, including video to this document, current news related to the topic, personal views in form of blogs, book search, journal serach, directory search ,image search ... an what not...An office with all the information at your door step...Also this office suite would allow you to save that "word" file or ppt in a briefcase in the gmail account and when you need it just start the presentation from the GOffice itself. Also it may allow you to publish the document on the web by just clicking a button.
You may also get advice from google answers for the document in no time. Possibilities are just limitless!
