Ergonomic keyboard
Apple Adjustable Keyboard is a split keyboard
An ergonomic keyboard is a computer keyboard. It has a more comfortable design intended to lower the chances of muscle strain and a lot of other related problems. These keyboards are created in a "V" shape. This can allow the right and left hand to type in a more natural position.

Ergonomic keyboards are great for low impact typing, but if you are right handed, the space taken by the numeric keypad makes you hold the mouse out at an awkward angle. This keyboard modification eliminates the problem.*Also visible is my Vertical Mouse which reduces wrist strain, and my Hayworth Zody, which I find to be an amazingly comfortable chair.
