A major advantage that often seemed to be overlooked in the rush from terminals to web pages is that if you pressed a key that took you to the next screen, your next keypresses would be queued up and they'd go into the next screen when it was ready. So if workers were following a familiar process, there was often zero latency when changing screens because they could just start typing into the box they knew was going to appear.

Web based things made this worse because you have to actually wait for the new page to load before you can start typing.
