The result is a desktop surface with a Logitech mouse. Apple having some intention and reasoning behind the design does not mean it is no failure.
No many people use their Logitech wired and wireless.
Logitech devices are useful but uglier than sin.
Apple’s objective was to create a mouse that will ONLY be used wirelessly and has no visible ports and ugliness.
So the only way you can do that is to put the charging port underneath.
The best way to do that is on a charging mat, but that charging mat for mice wasn’t possible at the time.
