Christopher Latham Sholes invented the Qwerty Keyboard as it has the most commonly used letters in the area for your index fingers to hit. I cannot see that there is any other layout that will be as efficient, personally.
If all modern typists had their chairs adjusted higher so that their keyboard is lower, they wouldn't keep dragging their wrists on the edge of desk or keyboard. I question that H & S are really doing keyboard users any good.
Sorry, off my soapbox now
