Ugh. Just because a UI is innovative does not make it necessarily a good thing. That should be obvious! When I first installed Windows 8, the first thing I had to do was disable the Metro versions of each and every staple app so they launched in desktop mode when run. Before upgrading to 8.1, the first thing I had to do every time I started up my machine was switch back to the desktop. I did this not because I'm low end and abhor all change, I did this because my machine doesn't have touch, just a mouse and keyboard, and because it's completely ludicrous to take up my entire (rather large) monitor to show things like a single progress bar when I could have that to the side to monitor while doing something else in a OS that supported windowed apps. Microsoft hasn't done a good enough job fusing their UI metaphors yet. It was incredibly ambitious to even attempt to do so, as interactions are so diverse. Regardless of ambition, though, in practice it's really a drag to force a half-baked attempt on everyone when desktop users are just going to have to go around adjusting things to be fully usable on the large class of machines that don't have touch support. I'll note also that, in spite of UI innovation in iOS and OS X, I don't have to depend on Siri to launch an app or only use Launchpad on the desktop. Apple doesn't do this because they know these interfaces aren't so good that they could forever replace what users have today. If LaunchPad became the only way to launch apps in OS X and by default all the built-in apps ran fullscreen iPad style, you can bet your life there would be just as much grumbling and moaning from those famed Apple customers as you're seeing today in Windows-land.
