They’re very smartly thinking that touch screens are the wave of the future so all OS from now on until the next major shift, will be touch screen oriented. This is coming out in 2012. The Windows Phone which is already starting to appear is using this interface. Most the reviews so far I’ve seen have been pretty positive.
I do think Windows 7 was the first OS they did that was mostly right. And I’ve enjoyed it. So hopefully this new OS will be even better.
