I don't know why he gets into the FLASH analogy when as he admits the headphone jack is not a harmful technology. The headphone jack was and is perfectly fine.
Maybe this will push wireless headphones, but I find this a weak excuse for removing the jack at this stage. How much better would it have been if Apple invented a new low-power wireless standard that blew the doors off of Bluetooth? An open one that they released into the wild and let all the players implement it. Instead they remove the headphone jack and give us $159 headphones that use plain old Bluetooth with a little "secret sauce" mixed in. I'm sorry but until Bluetooth becomes worlds better it won't be a true replacement for wires.
