For a start, older fixed-width dumb terminals and printers.  And even some
very new devices (tablet, smartphone) might have limited screen sizes.

And even if you're on a device that can display more than 80 characters, it
can be convenient to have several windows display side-to-side.

No, but it improves human readability.
