Many flourishes detract from usability (not all of them though). They're basically useless fluff. They don't help at all to get shit done which is what we want to do. Interfaces should be simple and utilitarian, predictable, changing for the sake of change is bad (I don't want to re-learn). Usually when an UI is stunning at first sight, it's incredibly hard to use and discover. UIs should fade into the background, you should just use them as if they weren't there. The less friction the better, and simple UI usually have less friction.
