The tie-fighter keyboard allows you type in a neutral, handshake position with your arms and shoulders supporting your hands. I consider this to be one of the lowest stress positions. As you can't look down to the see the keys, you do need to touch type to do use this; typing in passwords can, admittedly, be a bit frustrating but I'll take that over sore wrists any day.
I figure that we evolved, among other things, to pick berries rather than typing on a keyboard all day long. The tie-fighter vertical keyboard position is a lot closer to a berry-picking position than a standard keyboard.
