I appreciate your postscript. I don't use TeX or vim out of nostalgia; I didn't discover TeX until I was a senior in undergrad, and I think I didn't discover vim until after I finished my Ph.D. I use vim because it seems best for its tasks, given the way I think (though maybe I think that way because I'm old). I use TeX because I write math for a living and have invested a huge amount of time using it, so that it's become intuitive to me even though I know it wouldn't be for a newcomer, and I can't be bothered to break long-established habits until I know an alternative will be established everywhere TeX is.
