Newer interfaces aren’t always better
I was at the car dealer today, dropping of the car for safety and emission inspections. The service advisor brought up a VT100-style terminal interface on her computer to punch in the service details. She made an offhand remark about a problem with the computer system today, and slammed her way through some text screens on the numeric keypad.
If that system was implemented today, it would have a web interface. It would be more pleasant to look at, and easier for a new employee to learn. And, yet, once that employee became proficient, I’d wager that tasks would take longer using a web interface compared to the original terminal interface.
