Has anyone ever actually been bothered by having an audio jack? Having to plug in an adapter is not futuristic, its annoying.
Lint. Headphone jacks and lightning ports on every iPhone I've ever owned would always stop working properly after 6 months to a year of being carried around in my pocket. (Sort of) easily fixed with a paperclip to pick the lint out of the port, of course, but annoying and the headphone jack was harder to clean than the lighting/dock connecter port.
