I see absolutely nothing wrong with USB-B or headphone jacks. I'm far from an Apple fanboy, running a Thinkpad with Linux and a Google Pixel 2 (and yes, I am pissed about not having a headphone jack.) I'm not just embracing whatever Apple says. But once I switched all of my machines to HiDPI, I saw the light. This, to me, is not a minor improvement in experience. It is a huge improvement in experience, and in my opinion essential for people who deal with languages that have a more dense script.
