Actually, I think Vista looks not only overdone (tried too hard to make everything stupendous) but also unpolished. And, let me remind you all, that
we had transparent titlebars in earlier builds of OS X, but it was taken out (thankfully) due to how annoying it was after the "neat" wore off. Ditto for the almost 50% transparent menus (which are not in this picture). It may look cool at first, but it really is a stupid idea - it simply doesn't look good when you have dozens of windows open. Oh yeah, I almost forgot, Windows users maximize
everything so it wouldn't matter. Makes sense now.
