I've gotten annoyed several times by my Finder window clutter. Sure, you can just drag over a window, but sometimes windows get hidden underneath others. I'd say this is more functional than what Apple has solely with mouse movements, but it might not be as useful as using a keyboard in addition to a mouse. Of course, some people prefer one or the other, so this is still a really useful innovation in my opinion.
