Use for dual monitors?

I've had my Radeon 9700 Pro for a while now and still haven't found a real use for the dual monitor support. I've been sitting here staring at the extra desktop space just wondering what a good use for it would be. I would use it for internet/media while playing full screen games, except that most of the full screen games I play bind the mouse pointer and crash when I alt+escape. So if anyone actually uses dual monitors, I am curious to hear what you use them for.
