The killer feature is emacs lisp. Once you’ve gotten a handle on the general, day to day use of emacs and the packages in your quiver the next step is to learn the language that powers the system. This will open up an incredible amount of power and customizability. It will change what you think emacs is, fundamentally.

Writing your own functions, modes, and packages is the thing that makes emacs emacs. Right now, you configure your system. But once you learn emacs lisp you will be able to customize it. This is a huge difference.

Oh man, if you had this connected to your primary monitors and used it just for the minibar and completion results and such, somehow, that would be incredible.
