What to do with two monitors?
 

Ill be posting this thread in both videogame and tech talk as Im looking for suggestions for computer use and videogame use. Im about to purchase a 19" Widescreen LCD that will be used for both playing the 360 and a computer monitor. My other monitor is a Dell Flat screen 15" LCD. Its still relatively new so what can I do with it. Ive heard some people use two monitors at the same time for various reasons but I dont know what reasons exactly. So what can I do with the two of them?
