Weird.
I have no idea what I’d do with 2 monitors. I don’t do anything cool on my computer.
Its like that saying… once you go black you never go back…
same thing with duals… once you have them you’ll never go back
I have 3 19" LCDs on my desk 
I used two have two huge CRTs. Then XMas came, and I decided I wanted to upgrade!
I do a lot of computer work from home, so when I’m not working on computers, they’re all for my main rig. But, if I need to work on someones computer, I just use one or both of the extra ones
3 X 1 FTW! Its nice to have three different tasks going on 3 screens. Ebay sales on one, internet on another… and file browsing for the 3rd
Yeah, mine is more for the comedy of it. Work tends to get pretty boring. If I ever really used my work computer, the 4 screens would be too much, but since it’s mostly there to monitor AIM from coworkers, email, a server and a web browser or two, the extra space is great because I can have it all up at once.
