You must have a lot of faith in Microsoft when you consider giving up your stable Windows7 in favor a dot zero release of an Operating System that in a lot of way still looks like Windows8.
Unless I can see any kind of track record that it is indeed stable, all the cloud crap can be disabled and they actually put back Themes so I can get rid of everything "modern" or metro or whatever they call this nonsense, I am very happy sticking with 7 for at least the next 5 years.
