This sounds very similar to DOS vs Windows. How many DOS (i.e 5250) apps are
still being used? The number of Windows platforms out there certainly seems
to indicate people prefer GUI. I recently helped replace a DOS app with a
Windows/AS400 app because the customer felt that their seasonal temporary
employees would be able to learn it faster, and because it can show more
information in a single screen than a 24x80 or 25x132 screen. And so far,
hardware prices have been dropping fast enough to make it affordable.
