As someone suffering from RSI, I’d buy this in an instant if it worked with MacBook Pro and connects wirelessly (so that I can rest the keyboard on my lap). Promising !
BTW: I made mine for my own tastes:

As for holding in your lap, the cord on mine (kinesis advantage) is long enough that I can comfortably take it off my desk and put it in my lap. YMMV, of course, depending on how you have your desktop set up, but I doubt that's an insurmountable problem.
I tried the "you don't have to bottom out" approach on several mech keyboards with blue switches, but never really felt it. I still had to consciously wait for it to register the click, while normally I'd be over the next key already.
