Tip: Remap the Caps Lock key as a Backspace

For some time now I’ve been using my Caps Lock key as Ctrl (probably the Caps Lock key is the most useless key in any keyboard) but after switching to the Colemak layout (part 2) I’ve come to the conclusion that the Caps Lock can be very useful if configured as a Backspace key. Having the backspace on your left pinky allows your finger to travel less and not loose the resting position in the middle row, making writing even speedier than before. It is my belief that this is even useful for those using a traditional qwerty keyboard. In the mac you can try it by using a little software called Seil. What do you think? Do you use the Caps Lock as another key?
