> if you stretch the definition of TUI a bit, the Bloomberg terminal is a fascinating example

The Bloomberg Terminal uses several different UI methodologies depending on use case -- many functions (applications) are absolutely TUIs whereas Launchpad is more mouse-driven.

I worked as a UX designer at Bloomberg and when we had to modify existing functions we were careful to maintain shortcuts and keyboard navigation. In a couple cases we even ended up re-implementing UI bugs that one or more users had grown accustomed to. I've never worked anywhere quite so committed to backward UI compatibility, but that came at the expense of a steep learning curve.
