I don't have an issue with iPhone 5S - on the contrary. I also mentioned that I still use one.
As for the audio jack, that complaint will be on - it is not the optical disc equivalent. Apple still includes the jack in the iPod, MacBooks and iMac lines. Why didn't Apple show its "courage" in all their products.
I am not against BT headphones - they were available even before the audio jack was removed. It was always a choice, made better with the very good AirPods. There was no point in removing the audio jack - and the protesting fanboys sound like the proverbial dog in a manger.
the iPod Touch was last updated months before the 6S came out (which still had the headphone jack).
regarding Mac: there is a combination of small reasons that tell me why Apple is still keeping them:
1. you don't gain much battery life from removing the headphone jack and filling that space with battery because intel chips are power hungry.
2. there are still bezels/room in these products, which means it isn't a huge challenge in keeping the headphone jack in the design.
3. desktop speakers generally are assigned to one computer. you're not constantly unplugging the desktop speakers to plug into your iPhone for example. this 1-to-1 relationship between the computer and the speakers means it makes sense to keep the headphone jack. asking users to switch to wireless desktop speakers doesn't make sense. why would you pair with desktop speakers every morning when you turn on the Mac mini?
4. large chunk of the Mac users are pro-audio users. looking at how they use a Mac for audio production (spending 8-14 hours working with audio every day), wired headphones make more sense than wireless in these situations. of course, some pro-audio users probably wouldn't use the headphone jack and instead use their own DACs and pre-amps, but if you include similar users such as film makers, a headphone jack makes sense to them.
5. an adapter would use one of the usb ports. generally with iOS devices, you don't need to use a port (except when charging). but with Mac users, USB ports are essential to a lot of use cases of the Mac.
i'm not saying Macs will never get rid of the headphone jack. i could definitely see the new Macbook removing it first. followed by the MacBook Pros. hard to see future Mac minis and Mac Pros removing them soon. iMacs would need built in speakers that sound just as good as HomePod before they remove the port, but could also see them including one more USB-C port and a headphone adapter (though that's sort of a lose-lose situation).
