Akshualy, in between the magic mouse and the hockey puck was the mighty mouse. The almost ergonomic one with the 360 degree scroll ball that always failed because the white plastic around it scraped the gunk and dead skin cells off your finger and gummed up the scroll sensor.
Eta: if they made the mighty mouse touch sensitive like the magic mouse and removed the ball, they’d have room to put a charge port on the front and get those side grip buttons too. Only down side would be the height/thickness that makes it ergonomic in the first place
Oh you want Nickey Mouse, sorry all we have is Mickey Moose.
