Is POE really relevant in the consumer space? All of my laptops get power and wired data through their USB C port. Does it make more sense to just send data over USB C? For example, my Chromecast gets power and wired ethernet through its USB C port. (I have an official Chromecast power brick that I plug an ethernet port into.)
