Comment 2 for bug 349297

when you have many windows on your desktop the focused one doesn't really pop out from the rest because focused and unfocused windows are too similar. You can see what I mean in the attached screenshot, on the top you see the human theme, both borders are really different you get instant feedback on which window is in focus, but with dust on a desktop cluttered with windows this kind of feedback is not as quick. (the screenshot is comparing functionality, not.... style..;)
