Having used a 3270 terminal in an extremely saturated system, it's amazing how much your way of working changes. Typing a full page of code, checking for typos, doing a test run in your head, then finally pressing Enter and sipping your coffee while the system took 1-2 minutes to process the screen. As soon as it was upgraded, we reverted to the normal workflow of pressing Enter first, the correcting typos, paginating instead of searching, debugging live instead of in our heads, etc. I don't think we were more of less productive either way, they're just different ways of working.
