The concept of living in emacs makes more sense when you think of it as an operating environment in its own right, and not just another application. You can think of emacs as a framework (that happens to be awesome for manipulating text by hand, and at least adequate at doing it in an automated manner) upon which a wide variety of tools, or, if you will, apps, have been built. The tools vary considerably in size and in how well they integrate with each other. Often the tools can be swapped in and out according to your preferences or needs: different in implementation but quite similar in spirit to the do one thing and do it well aspect of the Unix philosophy.
