So what? Window 8.1 will have a start button that... still does not open start menu, but brings you back to shitty start screen. And will have option to run desktop by default, but NOTHING other will change about usability and start screen enforcement. And 8.1 will be even slower, but they will hide it behind hibernation (which sucks too).
Really, what's the point in supporting such crap by making apps for it?
