Contrary to popular belief, the QWERTY layout was not designed to slow the typist down,[2]: 162 but rather to speed up typing. Indeed, there is evidence that, aside from the issue of jamming, placing often-used keys farther apart increases typing speed, because it encourages alternation between the hands.[11]
A feature much less commented on than the order of the keys is that the keys do not form a rectangular grid, but rather each column slants diagonally. This is because of the mechanical linkages – each key is attached to a lever, and hence the offset prevents the levers from running into each other – and has been retained in most electronic keyboards.
Do we have any studies done on ortholinear keyboards being more ergonomic?
Oh wow, Big QWERTY here, taking a jab at Big Staggered.
