Actually, that precisely what I am loving. I've been using Windows 8 for a couple of hours now (I am typing this from the Dev Preview) and never once I HAD to go to Metro. And, I've just been waiting for this kind of non-intrusive integration between the tabled paradigm and the PC one. I do want to use a tabledt instead of a laptop because of its size and the advantages of a touch GUI, and turn it in my main office PC by just docking (implying real monitor, mouse, keyboard). I don't want two machines and two OSs, I want one machine powerful enough and one OS that transforms as I need it.

I agree that Metro is not good for mouse and keyboard. In fact, it seems to me that's exactly the point with Windows 8. I am just loving this.
