Windows 8 is a good idea for touchscreens/tablets/phones. It's not a desktop OS, that's the issue. I haven't used it so I don't know anything about bugs/non-optimization/etc. for those systems, but the way the whole thing is designed, and the way the move it without any visible change to those platforms, makes me believe that if it is reviewed in the better format (phone, tablet, other touch screen) everyone would have a change of heart about it.
