I love Emacs and have been using it for years but whenever I want to make a really quick edit, i.e. writing a git commit I almost always reach for vi because by the time Emacs loaded I would've been done committing with vi, at least with a slower machine.

I know some people run Emacs in daemon mode, but it's not always convenient to do that

This and when I ssh into any machine, I know there will be a vi at the very least
