Yes, this. When I first heard about OS X all those years ago, I dismissed the ideas as eye-candy until I actually played with it. I quickly noticed how much thought had been put into what was conveyed by all the little animations and finesse touches.

The same thing applies here, I think - I watched the video expecting to see the exact opposite of what I want in a UI, but came away impressed by how much thought and consideration has been put into it.
