I also do not agree with TFA that the keyboard layout does not really matter.

I have switched a few years ago to Dvorak. I do not think that this has changed much my typing speed, which has never been important for me. However, it has greatly increased my typing comfort.

Now I consider that switching to Dvorak was one of my best decisions and I only regret that I have spent decades using Qwerty without trying alternatives.

Of course, using an ergonomic keyboard is at least as important as the key layout.
