Have you looked at the pictures...? The cases are HUGE. I imagine that the keyboard itself is a small fraction of the case, electronics and all the controls. Were it a flyweight plastic case, the action would make a bigger difference, but with a bunch of electronics and a solid looking case, the action itself is only a small percentage of the total.
