First time I saw it was with a touchscreen device and I didn't find out that it was touchable until I had googled how to add more users to WinRT device.
Therefore YMMV
EDIT:
Negative karma for pointing out an opposite experience with a device?
Our opposite experiences just goes to show that UI qualities are subjective, and until someone releases scientific studies (none of this "many users" crap) that go against Microsoft's own user testing, I don't see why they should ditch their Metro experiment.
Therefore YMMV
