GNU Emacs is the greatest piece of software ever written, it enables you to do incredible things, move your productivity far beyond what you could achieve with any other software package, it is a text editor, web browser, file manager, file viewer, dictionary, shell, programming environment, and many many other things, all in one. It is the father of Free Software. Get acquainted with GNU Emacs once, once you feel it's power, you will never go back, and laugh at any other measly software, allowing you to only accomplish a fraction of what you can do with GNU Emacs.
