I want a metal back phone
Steve Jobs did too, they still needed a plastic window for some antennae on the OG iPhone, then went to full plastic. It has become worse now, the back isn't just for wireless charging. It is also for NFC, UWB, and often cellular/gps/wifi/bluetooth may share antenna connections through the back.
Right there with you though. NFC could probably be packed in a band at the top of a phone. UWB seems of dubious value thus far.
They don't even need to push an update, they just need to send a kill command from their activation servers.
