Cool. This makes sense. While the EM, required for charging, has plenty of overhead, the magnets required for physical attachment do not (otherwise they would be too strong when used without the case).
This is one of the most exciting things about the 2020 model in my opinion. It simplifies charging and brings the best from both worlds (cable, wireless). Current wireless charges do not allow for phone interaction during charging. These will. Also car setups will be much more simple.
So Apple Silicone Case $99 and leather one $109?
