The first point is true. The second point is false -- it does matter. Saying that X is less important than Y can't be used to argue that X doesn't matter at all.

> If I am building a business or a product the last thing on my mind is what text editor we will be using. It is so ridiculously insignificant in the grand scheme of things that seeing people focus on it is beyond comprehension.

That's true in general, but there's an exception -- if you can improve the efficiency of editing, you might make a basic change in people's thinking and become a millionaire as a side effect.

Guess how I know this.

I see your point in people evangelizing VIM, Emacs, Apple, whatsoever, but... who cares? Let them be. I don't see, why you try so hard to prevent people from being happy and enjoy little things in life. Why does everything have to be insignificant, because something else is so much more significant? I seriously don't get your point there.

Let people love their editor, even if it is insignificant to you. People actually are more productive, when they are happy using a product they like, or could you seriously imagine writing code/surfing the web/do anything with the on-screen keyboard? Even you would get frustrated and would hate your job. It does matter. Maybe not the productivity-wise, but definitely how you, as a person, feel.
