I did use Emacs for several years before moving on to something more ergonomic. I still have muscle memory for several of the more common keystrokes.
I haven't really felt like there's been a Truly Great editor available since Brief, which I stopped using because they never upgraded it from DOS to Windows.
It's not about "getting my head" around something. To the contrary, I am very good at picking up new software and using it, whether it's designed well or not.
It's about having seen what a REALLY powerful editor can do for you, and having other editors never really live up to that standard. SlickEdit is close, and even better in some ways than Brief was, but it's not perfect.
So did you actually understand what I wrote? "Stockholm Syndrome" applies when you've been abducted, and you fall in love with (and defend the actions of) your abductor. I'd say you're not disabusing me of my original notion.
