I remember airport hostesses when they used it to get your boarding pass from the mainframe, it took them 5 seconds and a few key-strokes like 3 letter of my name to get the job done. When they switched to web-uis some year, I vividly remember seeing them, 4 at a time on the same screen, trying to figure out what was going on. Took them 15 minutes and a phone call to get the boarding pass ready. I feel sad when I think about this.
