As many of you will know, QWERTY was actually made to slow typists down (to most Slashdot readers however, it seems to have been ineffective) so an alphabetic arrangement, which was the original arrangement of letters on a typewriter AFAIK, would probably speed typing were anyone to learn it. However, some of you will have heard of the Dvorak keyboard layoyut, this was designed with speed in mind locating the most-used keys in the easiest to reach positions.

This seems to be almost stuck in the middle of two ideas: QWERTY being well-known; DVORAK being supposedly the best for speed and ergonomic typing. I'm not sure why anyone would buy this keyboard (or use this layout with another keyboard) although it could come in handy for teaching children to use computers - I know when I was first introduced to a computer I couldn't understand why the keys were where they were.
