Suddenly the horrible "tiles" dashboard brought up by the Windows key made much more sense to me, was more fluid than I anticipated and after about 10 mins playing on the laptop I walked away feeling "Yep, this is exactly how a laptop should be."
I was really surprised. Found it instantly intuitive and a faster way to navigate my way around the computer.
There are also a slew of more advanced keyboard shortcuts in Win8 as well that make me happy that Microsoft hasn't forgotten about keyboard-driven folks.
I know there is a lot of Win8 hate going around, but so far, I think it was a good move. Very curious how Blue Sky (8.next codename?) turns out though.
