Just curious what is the perceived benefit of ditching the headphone jack besides possibly making the phone even thinner? I'm honestly asking because I don't get it, but it does seen many people are excited for the jack to go away.
I think people see it as Apple being "ahead of the curve" or similar nonsense, and compare it to them ditching the floppy drive in the iMac decades ago or ditching the optical drive more recently.
I for one like being able to use any set of headphones with my phone. There's little to no reason to get rid of the jack. It takes up almost no space, doesn't cost much, and is wildly useful. Floppy drives and optical drives were bulky, cost more (relatively) and were clunky.
