I find a lot of the behaviors of these UIs to be surprising in an undesirable way. When a UI does something unexpected I should be surprised by how much sense the interaction has, rather than the novelty of it or a cool animation. I should be able to anticipate the behavior in a future context. They are touting this supposed underlying physical metaphor (almost as if that is their own newly developed idea in UI), but it sure looks like a mask over the fact that they just threw in a bunch of shiny animations everywhere with much less regard for physical metaphor and reproducibility than one should expect.
