This would probably be better in Hardware, but anyways to answer your question: Many people use dual screens if they work in business and have to view full-screen spreadsheets, and still want another screen to do other things on. If you want to compare 2 pictures side-by-side, you can use a dual-screen. Basically, it's not like having 2 screens, though. It's like instead of having a 1024x768 resolution screen, you have a 2048x768 screen split in half. You need a newer graphics card with proper connections (2 of them) and you need 2 monitors, of course. Then, you can just make a dual-display in your display settings.
No pessimist ever discovered the secrets of the stars, or sailed to an uncharted land.
