You know what the real problem is? That they are still planning to stay within their iOS and macOS as separate entities strategy, judging from what we just heard yesterday from Intel execs. ARM chips will be inside Apple laptops next year.
Why? iPads are already as thin as materials permit and DO NOT use that stupid butterfly keyboard. Ditch the laptops and desktops!
Use only iPads as flexible (no pun intended) workstations, and iPhones as complementary data/meta-data acquisition devices (3D scanning, imaging, GPS module, sound capture, etc.) How come they cannot see all the advantages of using all the sensors inside an iPhone to digitize an enormous amount of information from reality, and the iPad to process it. That's it, those two tasks could keep hardware lineup simple.
AR is only one of the hundreds of applications for that combo, and it's just being used as a marketing tool, when in reality fields like medicine, engineering and the creative arts could integrate all of that technology to really advance the way we create, compose, design... even that Watch could integrate itself in workflows like the one being used on other devices, like keeping music tempo using vibrations sent to your body, instead of using sound cues.
But we don't get that... greed drives that company now and they want you to buy laptops, desktops, iPads, iPhones, etc. and milk you out for as much as they can.
