[Udate] Mr. Wrona is apparently also inconvenient for the Daily Telegraph's Harry Wallop who seems to now hold the record for most recent repetition of the urban myth that is QWERTYnomics;
...typing using a Qwerty just isn’t very quick. Also, the spacing out of common pairings of letters is responsible for millions of people developing repetitive strain injury.
There are many other machines that allow people to type more swiftly and safely, most notably the Dvoˇrák board (invented by a distant cousin of the Czech composer), developed in the Thirties. Crucially, this version allows your fingers to jump and stretch less and your left hand and right hand are used equally – with a Qwerty, your left hand does well over half the work. The world record for typing on this version is more than 200 words a minute, a speed that would cause snapped fingers with a Qwerty board.
