As someone who mostly lives in Emacs, I like it. If I'm away from a machine, I can SSH into it and carry on with whatever I was in the middle of.

It's also nice to set emacsclient as EDITOR, so that e.g. running `git commit` will open up a buffer in the existing Emacs session. This is especially useful since I use shell-mode, and it would be confusing/weird to have new Emacs instances popping up when I'm already in an editor! (They open in a "window" (i.e. pane) in the existing "frame" (i.e. window) instead)
