> But that doesn't explain why it would be preferable to remove the headphone jack in 2016 and have people be used to it by 2017, rather than the same but a year later.
Perception. People focus on something more when it changes, and there's only so much focus to go around. Remove the headphone jack a year earlier, and it's not a "change" that it's still missing from the next model. So focus/attention can be more concentrated on new features that Apple brings to the newer "10th anniversary" iPhone.
"Yeah, but it still doesn't have a headphone jack" is a rational reaction, but not the one that most people will have. It's irrelevant background noise, compared to the shouts of "Look at all the new shiny!", which is the reaction that Apple's going for.
