I work for a company that for years has had a very old-school, terminal style POS. Lots of key shortcuts. Like, black/white text terminal POS.

The folks who learn how to use it well navigate through it faster than the system can process their inputs.

The new system has lots of fancy GUI, but is slower, and the folks used to their shortcuts hate it. But it's so much faster to train people to use.
