Personally when using it in RP in a vm I found it unusable, the scrolling on Formerly Metro with a mouse didn't feel right, and when trying to use it as a power user, not having a start menu, somewhat annoyed me. I'm used to hitting the start button on my keyboard, typing something and then hitting enter, and the program appears, adding extra steps into that made it feel clunky. I haven't tried it on a touch screen device yet, maybe it is miles better on a tablet, but I personally will be avoid Windows 8 on any of my computers.
