Well she is an expert at vi, and even has a DOS port of it. She has a Unix background and got used to using it. If it works, why switch? As long as it works for her, I don't see the problem with it.
Expert? I am? LOL! I never thought of myself as an expert, but I was proud of how I learned it, which was completely on my own, more or less at first, then John showed me some good ones I didn't know. Basically, I played around with it and found it to be fun to find out what key combinations did what. Owls love a challenge! ;)
And I think you meant to say JOHN has a unix background, because I don't, but he does and that is another reason he chooses VI. But I'm always fairly partial to what John shows me how to do or can help me with, makes it easier to learn on my own, and I learn most computer stuff on my own.
He even wrote me a program called WRAP, that I can use in VI to automatically wrap my text messages when saving my email! WHEEE! Owls like VI!
