Emacs is my shell. You don't have to stick to elisp either, you just need a little elisp glue. (The Emacs interface for the GNU Guix package manager, for example, is written in Guile Scheme for the most part.) Emacs is trivially extensible and whatever I make it do can be used in other sub-applications. I can evaluate code wherever I want and change the system at runtime. It's quite a different feel compared to having "unglued", ununified applications.
