The keyboard and mouse should both charge by sticking to the rear of the iMac with a big magnet, that would be pretty neat and tidy when you want them out of the way and make it easier to transport too.

I have one of those for the original roach mouse. It it was awful.

They could do qui2 and that wouldn’t be awful charging wise, but now the puck is gonna stick to your mouse. You can’t really wireless charge your mouse and move it. You could make a mouse pad with 500 charge coils but then you’d just try to make Apple’s failed AirPower. It might be enough for a mouse, but it’s gonna be stupid expensive and stupid inefficient. Logitech has their G power system but that’s $120 without a mouse.
