For me, window managers are mostly just a convenient way to arrange a baroque collection of web browsers and terminals... Occasionally, I use file organization/navigation or a couple other programs that are helpful in my job. But ultimately, I just need a minimal window manager that gets the hell out of the way. (in fact, after setting up awesome rotating Moebius wallpapers, I mostly don't see them, as they're almost entirely buried under the web browsers and terminals.)
