At one time EMACS was a great asset for me to use, but I prefer to think I have evolved along with the available software, and have for the most part moved on to newer software. Not to say that there is anything wrong with using EMACS, I would just rather use a mouse to manipulate text than constantly hamering on the keybord. I am not very fast at typing so I prefer a less keyboard intensive editor.
It's been said that Emacs is an environment, not a text editor. I suppose it serves the same purpose in text-only environments that a window manager does on a modern X display. In that respect it's evolved to accomodate many functions.
As to the mouse, I'm exactly the opposite. I'm a touch typist. If I have to reach for the mouse to do something, it breaks my train of thought as I switch from one input device to the other and reacquire the home location. If I'm manipulating text, I want to do as much as possible with one device only.
