I use dual CRTs. adn if you ve ever used them, you can tell how much easier it is. I am able to keep winamp, tirllian, and system monitors on my left monitor, while keeping all the real estate free on my primary monitor for word, excel, firefox, games, etc.
It REALLY helps when I need multiple information, like entering infor on a form online, I can look at one scrren then the other instead of having to close my windows. Also, when I write my papers, I have my research on one monitor and the paper Im writing on the other. It helps from having to move around and lose my thought in trying to switch programs, especially is something is tking forever to load.
I know it sounds weird but it is REALLY usefull
