Correcting mistakes on a pen is labourious, same with a typewriter. I find Notepad severely limiting too when it comes editing text (how do I set a mark? how do I kill the current line? or what about just the current word? how do I access the kill ring?) not to mention that all of the keybindings are wrong.
I can use something other than Emacs if I have to, but it all feels like I'm tying both arms behind my back and writing with a pen held in my teeth.
Well that's too bad, as people have done some serious writing using simper tools - a pen, a typewriter... Isn't Notepad (on Windows) a sufficiently good tool to type, say, a novel in? Less distracting it is, for sure. (Well, I heard some people say that Notepad requires an OS to run, whereas Emacs is an OS in its own right, but really?)
