The ones who always call Bill gates as a legend and Windows a revolution will have a hand to test this thing so easily. The concept of the next to be Windows has been leaked to the internet and is available for download. Also have a look at this before you go ahead and download it.
For I believe everyone has their own perception and thinking process so the best thing I would like to say here is decide, is this new version worth your money or a rip off of Ubuntu or the Mac OS. Have a look.
Do let me know what do you feel and to get a free version of the above Windows do a Google search you’ll get it for sure(via torrent).
