I just got Microsoft Arc Touch Surface Edition an have been using it since yesterday. Takes a bit of getting used to. Scroll wheel being flat is harder than a raised wheel to find but once in use the haptic feedback is good. Only issue so far is it stopped working once. Bent it flat and back Off/On and it came back to life. Less contact area beneath the mouse than my previous one seem to make it glide a little less smoothly across the desk. Looks super cool though.
