I'm a computer programmer and have been using multiple monitors for years now. In the past it required multiple video cards. Now most video cards support multiple monitors out of the box. The one I'm currently using at home supports up to 4 monitors (I'm using 2).

For programming, I can have the code up on one screen and the application I'm working on running on the other screen. This allows me to "step through" the code and see exactly what is happening with the application.

I've also set up the computer at my Church with a "dual monitor" setup. One monitor and the overhead projector. This allows Powerpoint presentations to be run in "Presenter Mode."

And yes, you can move things between monitors; it's essentially just an extension of your main desktop.
