Have you ever had to run a debugger or see some real-time status information while the main screen is filled with a graphics window? Say you're writing a 3D first-person game or an immersive flight simulator, or making improvements to the X11 renderer, and you can't display one of your fancy terminal emulators at the moment. You want to print out a portion of the scene graph, or you need to single-step through some tricky logic. Solution: a second screen, often one which doesn't depend on cooperation from the GUI subsystems.

Though my example may not be the original poster's intention, there are are many good reasons to have a barebones display on a separate screen. There's a reason those terminal programs are called emulators-- they only strive for the ideal.
