Microsoft scaled back a lot of their tablet functionality because consumers didn't like it, and of course Apple started to copy Microsoft's tablet functionality shortly thereafter. I think maybe, Windows X will be more touch based instead of them trying to meld them into one OS. Only the core will be the same, but the UIs will be split on the OS level. I think...but who knows, Microsoft often changes directions. All I know is that the Surface hardware is on par, and in many cases better than Apple.
