It's the "when set up properly" that seems to be the trouble.
I don't think it's unreasonable for people to be resistant to tech when all their interactions with it (as you pointed out, in your "in public" section) are miserable.

As an anecdote, just this morning, I spent 40 mins debugging the integrated camera on my girlfriend's laptop.
The fix ended up being uninstalling the "Integrated Camera" device from the arcane "Device Manager" menu.
That kicked off some hidden Windows system, which re-enabled the device, and now the camera was magically fixed!
She had been living with that broken camera for weeks at this point.

That's the experience that people expect these days from computers.
You and I may be able to tweak our devices to our liking, but most people are just stuck with crap :(
I'm not sure where we go from here -- so long as people are disempowered to truly own their devices, and tech companies keep pushing out rot, nobody will experience that magical "instant" feeling.
