What's interesting to me is that some users seem to "imprint" like this on the first serious editor they use.

I certainly did with vi. I've jumped editors a bunch of times and still use others for specific tasks, but always come back. I'm guessing it is some combination of learning something complex - the first thing in a new area you study tends to inform how you look at other things in that area. And muscle memory.

FYI, on the Mac, BBEdit handles huge files like a champ.
