My first exposure to Unix was in the early nineties with Sco Unix. Of course it was vi for text editing. As the first editor I learned for Unix it's been hard to abandon for me. I call it vi hell when I fat finger commands. It's been to hard to break away from it, so it's what I still use. Of course there's variants, right now I'm using vim. At some point I'd like to get used to something possibly better, but I always fall back to vi.
