Because Windows 8 is kind of a hot mess? If they could jettison all of the holdovers from Windows XP and replace things like the file browser and command console with "Metro Native" apps, it would still be pretty to look at, but painful to live with. If you want to talk about leading edge, look to webOS which was ahead of its time in significant ways.
