Let me just say, when I purchased my new computer system late last year I elected to get the multiple monitor package. I can't tell you how much I love having more than one monitor. I could never go back to just one. Just can't do it.
If you do not have one.... GET ONE!. You won't regret it.
Back when I was lobbying for a second screen I came across a study that suggested adding a second display results in a 30% increase in productivity. I'll never go back.
Twin apple 27"... I don't know I could go back to working on one anymore. To convenient to be able to have everything you need (and im a sysadmin, so thats a lot) up at once, no need to hunt for windows
Mine is nothing spectacular, but I like it. I have one 22" in the middle with a small 12" to the right and a 13" TV screen to the left. I also have a TV card in the computer. I can surf INGO and watch two TV shows at the same time...not that I could ever process that all at once anyway.
I tried to drink two beers at the same time last weekend....I kept hitting myself in the face with the one in my left hand, I don't think two monitors would be a good idea for me.
The only time I use multiple monitors is when I'm running a projector from my computer to watch a movie. Other than that I've tried using more than one and always went back to one due to the fact that I hardly ever use the second monitor, and that it takes up that much more space.
I do a lot of programming and design. The ability to have a screen for work and a screen for reference is really nice. I'm thinking about taking down the paintings and hooking up a 42inch flat screen as well. I watch all my tv on the internet anyhow.
Here is my setup.
Built the tower computer myself... and those speakers are hooked up to my 600watt kenwood surround sound system.
Yeah, it's pretty cool. I had a dual monitor vid card in my old XP system. I've heard of trouble with vista, not heard anything + or - about it with win7. Ubuntus newest release 10.10 is set up to run as many monitors as you can plug in....I run my TV through a slingbox(why pay for cable) hooked to my PC and use the smaller monitor to surf and read here while watching TV or netflix on the big one....
