The counter intuitive thing to keep in mind here is that the best animations are subtle, and very quick. There's a balance to strike, but good animation can make the snappy UI give just the tiniest hint of motion and smoothness, without detracting from the experience at all. Animations are meant to be subtle hints to guide the viewers eye, not flashy eye candy. Long animation times are _such_ a common rookie mistake, because the UI dev (or their manager) wants to notice the animation, when in the vast majority of cases, it would be better for the animation to be nearly invisible.
