What would this be used for?

I use these kind of text based ui's for internal tools where dealing with a full graphical UI is often 50% or more of the actual work. It's easier for the novice user to use tools with basic text based user interface than to use command lines, but it's much faster to develop than a WPF app (and it's multi platform)

CLI applications that need a TUI

Avoiding your mouse. TUIs can be far faster than GUIs when you don't have to take your hands off the keyboard to reach for a slow mouse.

Rogue-like games.
