And, honestly, I'm glad with their push for USB-C, no audio jack etc. Most companies are stuck in the status quo due to the chicken-and-egg problem but Apple is willing to be the first mover.
Audio jack is another one. I have some nice open-back headphones and they don't have USB. I think it's actually fairly unreasonable to expect the entire audiophile headphone market to convert to digital; it makes more sense to do the DA conversion on the phone/computer, especially since some audio sources are analog anyway.
