The AirDrop and Hotspot issues described are spot on. The success rate for these is like 40% to 65% (the latter if you’re lucky). These features require doing a dance of airplane mode, disconnect from WiFi, go to Settings and fiddle with the toggles, etc. When it works, it’s like magic. At other times, it’s a big joke on “it just works”.
Text selection and the trials to just move the cursor quickly and accurately: it’s like Apple has no senior management that cares enough (looking at you, Craig Federighi), no QA (this is obvious truth to every user) and no money to spend on making things better (don’t let the stock prices fool you). FWIW, I know of slower and fiddly ways to move the cursor somewhat (press space, hold and move or place finger on the text, hold and move).
All these issues persist for years or decades because senior management does not care. I can’t think of any other rational explanation.
