FWIW, I would not classify myself as "pro 3.5mm jack". I'm eager to see what Apple has come up with, they usually have things fairly well thought through (not always following the path that some people want, but they do usually have well-reasoned arguments for why they did things the way they did). But I am concerned about being able to charge and listen at the same time - that's not a non-issue; it may not affect you, but there are solid use cases it does mess with. I've played a lot of Ingress over the past few years, which involves a lot of walking around (it's not always clear whether I'm out walking to play Ingress, or playing Ingress as something to do while I walk - either way, the encouragement to go walking is not a bad thing). The game eats battery, and I'm generally either listening to the game, or audiobooks/podcasts, or both. I'll have some moderately good wired headphones (Etymotics with custom earmolds) plugged in and an external battery pack plugged into the Lightning jack at the same time - this arrangement isn't just "nice", it's kind of vital for this use case (I've also used this setup to listen to audiobooks on long walks that were started with my iPhone's battery already somewhat depleted after a long day). So, I'll take exception to your assertion that charging and listening at the same time is a non-issue; there are very good uses for it. I won't complain (much) if my existing headphones need an adapter, but I don't want to have to choose between listening and charging. As I said, I am quite eager to see what Apple has come up with as a solution.
