Not a great fit for mobile uses because you don’t want to move around too freely. that's a false argument because the inclusion of an audio jack does not prevent the use of bluetooth. i use high-end headphones at work, home, and in certain travel situations like a plane and use bluetooth everywhere else like with my car and wireless bluetooth speakers. you said the 3.5mm jack would not be the interface designed today, but yet, you didn't come up with an alternative. the sound with a proper dac and headphones and a physical audio jack is incomparable to bluetooth and bluetooth headphones. and having the physical audio jack makes it much easier to do what i want with the audio when i want. whether it's attaching to a bose bluetooth speaker or outputting audio to sample on my op-1, it's the best of both worlds. the problem i have with apple is that they have never given a compelling and logical reason for removing the audio jack. my lg v35 has the audio jack plus a high-end audio dac and yet the design is every bit as sleek and compact as the iphone x phones, in fact, maybe even more so because the camera doesn't protrude. so all of this is pointless arguing simply because apple can't even answer the question of "why", as in why even remove it in the first place.
