I use a keyboard that has a similar layout to that in the images above (ctrl to left of A, tilde on home key at top right etc). It's called the Happy Hacking Keyboard and is made in Japan by a Fujitsu subsidiary: see here http://en.wikipedia.org/wiki/Happy_Hacking_Keyboard. It's extremely expensive (~$300 or so) but has amazing key action and having gotten used to it I would never want to use anything else
