If you can touch type then the safetype keyboard could be for you. Rather then using a standard flat keyboard layout the safetype splits the keyboard in half and puts the keys vertical which supposedly is a more natural way your hands function. It is built to reduce RSI (repetitive stress injuries) making a more comfortable typing experience. Costing $295 it is priced on the highend, but if you suffer with pains while typing and after then this keyboard might sort you out.
