Even without the limiter and prompt, this still gives you several word processing style extensions to the basic INPUT.  For example, arrow keys work, as does the ability to use ALT+ASCII values to directly enter characters via their ascii code (such as ALT-1 for the little smiley face icon dude), as well as the ability to paste code into the input with CTRL-V.
