Shortly after Apple released the button-less iPod Shuffle, I wondered whether or not Apple had plans of killing the dock connector.They did eventually, but not in the way I expected.
The Lightning connector is now the iPod, iPad, iPhone, and even accessory connector of choice, but I had theorized that Apple would integrate all of the that functionality into the headphone jack. Funnily enough, here we are six-and-a-half years later and Apple is rumored to be killing the headphone jack.
