Animation should enhance and enrich the UI, not make it "look fancy". Apple gets this perfectly. The squeeze animation on iOS's volume bar is a great example. P

  Apple is missing a few bites from its perfection: They use these sliders, realize they could be ambiguous, so add an accessibility setting for the on/off labels. Then they have these fancy animations where holding a slider even elongates the button "providing feedback", but this is just wasted since your finger is covering the button, and fingers have no eyes! But still, it's a slider, so you'd expect that if you slide your finger over it, it will move. Not so fast, this only works if your started sliding from the slider, not from a side outside it (which would still work in the "real" world.). But if you start at the slider, then there is no point in sliding, there is simply not enough width for that! Also if slider's button is to the left and you swipe from right to left, the sliders moves right! Take that, immediate fedback in the opposite direction, massive UX boost in a manner that's unexpected and doesn't make sense! (because it's not a real slider, just a check box of a different form)
