An alternative view of keyboard layouts

On a related note, I never understood how anyone could touch-type comfortably on a non-ergonomic keyboard. The keys are slanted in the same direction for both hands, even though the hands are naturally at different angles. For the right hand it works great, both for the left, the finger will run into its left neighbour when hitting a key above home row (e.g. R), and into its right when hitting below (C).
