Mad Catz is perhaps the only manufacturer that really pushed the envelope when they released their truly unique S.T.R.I.K.E. Even so although gaming keyboards featured several aesthetic and performance additions which aimed to improve efficiency/speed while gaming the design remained pretty much the same.
