Several modern Emacs modes have the same qualities as Magit, including great design and modal keybindings. For example, Notmuch is in my opinion the best email client of any platform (excluding Gnus for some really specialized use cases). Org is probably the other obvious example.

I think viewing Emacs as a text editor is too narrow-minded. Emacs is really a text-mode Lisp machine, a platform where editing modes are applications. In fact, some people's favorite Vi implementation is Evil for Emacs.
