How would it not be? -I don't need a dongle that I can lose. (You might never use your earphones with another device, but I do, so the dongle will need to get unplugged from the earphones at some point) -I can use earphones at the same time as charging. -A dongle is one more thing that can break. -I'm not stressing a port with something that it really wasn't meant for

Also, when I have a headphone jack, I still have the option to use a dongle or bluetooth, so nothing is lost by having the port
