As fryke pointed out, for me it's about Dock tidiness.
I prefer my Dock to show me only what is running. I don't want crap in there that isn't being used. I don't want to have to right-click, or click-and-hold to navigate a menu to find what I want to launch. When I'm working I'm more than likely using the keyboard. I'd rather not have to reach for the mouse just to launch, say, Terminal when I can hit a hot key (control-space in the case of Quicksilver) and type "TE" then hit Enter.
I guess it goes back to my always using keyboard shortcuts for everything I possibly could. I'm not much of a mouser.
