What changes when chrome OS launch?

We all heard about chrome OS, which in launching in July. How this is different from other OS in the market? Like Windows, Linux and Mac OS. First of all it is not another Linux in the market, it is totally different from other OS. It doesn't require drivers to install, it also not require any application to install in it (means no PDF reader, no Microsoft office), all thing is on net. But I am here for telling you what will be effect on market when it is launched. In my view the market share of Microsoft will not be affected more than 5-6%. The maximum use of chrome OS will be in  Internet Cafe's because the user wants only browser on Internet Cafe's and chrome OS is not anything else but a extended browser. In 2-3 months of time the chrome OS will be on every  Internet cafe's because it has reason also...  

first, it is free.

second, it is faster than other and we didn't have to install any thing extra in it.
third, it consumes less memory space than other OS. 

Google have also done a smart thing that only user who has a Google account can use the OS,

so there will be increase in the amount of user of Gmail. The Google is now concentrating on increasing its reach to the user's, the internet is bundled with the Google product's and the chrome OS will bring revolutionary changes in computing world. Now, the application's which were built as stand alone now they will be converted to web based. It will be helpful for the user because user doesn't have to carry his/her lapy with him and he can switch to any PC because his data is on net. Now, it generates one more issue of piracy, it can stop piracy also....
I will discuss this topic in another post briefly, so, till then keep waiting.......Thank you for visiting......
