Well, there's "green-screen" VT100 terminal apps, and then there's 90's Vintage Java/oracle-forms UI's and then there's modern applications designed with informed UX approaches.

The terminal apps, at least, have some history behind them and properly trained folks can be very fast with them.

But we're talking here about shitty early Swing-apps (or Oracle forms). If you've ever used one it can be incredibly frustrating. Moreover, people are usually just tossed into a role where they have to use these M-F-ing interfaces with no training. Who makes a table with cells too small to fit their content and where you can't resize the table? Oracle. That's who. And they're paid for it like you wouldn't believe!
