Something I've come to rediscover is how good vi/vim is on a slow network connection. Our sharp networking team route me from London to Sydney so I can remote back to my London PC.
Seeing what you type several seconds after you typed it is reminiscent of the 90s and dial up connections.
Having familiar vi keybindings in so many applications these days has been a productivity saver.
One editor which used to be great at this is sam, which was explicitly designed to work across slow links, by being split into a frontend running locally, and a backend being run on the target host: http://sam.cat-v.org
