I have exposé mapped to my middle mouse button, which i find very useful. But you cannot do this on the Magic Mouse (or whatever it's called) last time I checked, although I'm guessing there's a plugin to fix that. Still, it seems such an obvious feature to me, can't believe it's not included by default.
