I used Vi, and then Vim, for a good 15y before I switched to Emacs. I made the switch because I had heard that Emacs let you manipulate your buffers with lisp as one would any other data in a programming language. I find I only really do that when using Org Mode or REST mode, but I'm still glad that I made the switch. The editor is ... mine. Mine in a way that a professional's tool should be an extension of themself.

I've been thinking of trying evil, but I don't really miss the modal editing as much as I thought I would, and it's been another five to ten years.
