It's not merely nostalgia or availability. I continue to use emacs because it has the features that I want, where other software does not.

Some things I want out of an editor:

* Never having to touch the mouse in any way.

* The ability to customize any feature for my current project or mindset on a whim.

* No UI, as much as possible. Show me the content I'm editing and nothing else.

* A good, extensible, set of keybindings with a bunch of features for editing of raw text

I run my project in an IDE and will sometimes use a feature, but I generally don't develop there.
