After years of unsuccessfully trying to get people to use modern GUI based software, I had a minor yolo moment and replaced an entire factory worth of employee facing software with a text-mode curses interface. No mouse support, company banner using ASCII art, interface in multiple languages that you toggle with a control key etc. All instances are concurrent user sessions on a linux VM in the cloud, it runs faster than anything we've paid for and no one will entertain the idea of going back. Not saying this is a typical situation and we're only talking a couple hundred daily users, but still, food for thought.
