Well, being the trivia master I am, sometimes the standard keyboard is referred to as the qwerty keyboard. Some people think the Dvorak (named after its inventor, not the layout) is better. If you like the Dvorak keyboard, then you'll probably be speaking Esperanto someday.
I too am a master of trivia, and i know that the original tests which "proved" the dvorak keyboard to be superior were carried out by the US Navy in 1944, tests that were carried out by a time-and-motion expert Lieutenant-Commander August Dvorak -- guess what? He owned the patent on the Dvorak keyboard layout.

Tests carried out by the General Services Administration in '56 found qwerty to be superior, which pretty much killed interest in retraining people to dvorak.
