I love TUIs but one main reason for that is that they're keyboard centric. If I have to use the mouse it kills it for me, if both work then it's fine. I hope that modern TUI makers keep this in mind. What's great about the keyboard centric is that with a few keystrokes/shortcuts it's very easy to do repeatable work and takes less energy than hunting boxes to click on with the mouse.

TUIs aren't more inherently keyboard driven than well constructed GUIs. You can easily make a keyboard driven GUI that has all the shortcuts you'd add to a TUI. (Just don't let the "UX design experts" near it.)
