2 piece keyboards are REALLY expensive. Why not use 2 generic keyboards instead? Are there any problems doing this? I just tried Microsoft and Dell USB keybaords and it seemed to work fine with the shift key activating shift when the key is pressed on the other keyboard. If you wanted to get the size down one could fold the circuit board underneath so you only have the left and right side with no numeric keypad (that almost nobody ever uses). You'd have to saw the case of each of course. 1 cut for the left one and 2 cuts for the right one. Now you have a very portable, 2 piece, ergonomic keyboard. Why is nobody doing this? And if it breaks its so cheap and easy to fix/replace. You can get these keyboards everywhere. They're worthless! You probably have a few lying around right now.
