I know your point is slightly different, and I agree that the end-to-end control is a good experience for people, but I actually think the whole "just works" thing is over-stated. And by a large margin.
The amount of problems with Apple gear I've had - persistent wireless connections issues, breaking MacBook cases, OS installers throwing up black screens, batteries refusing to wake up from a complete discharge, back lights failing, antenna issues, home buttons sticking etc. etc. They cause me just as many problems (if not more, but that might be due to me having a higher proportion of Apple gear) than any other device from any other manufacturer.
On that note... Two things I dislike about my MBA...
The Wifi, drops all the time, far more than my phone and my old laptop. There was supposed to be an update to fix it, update came, made little different IMO...
Sleep. Something that is made a big deal of by a lot of people, to me it's worse than windows a lot of the time. Biggest issue? The frustrating tapping and key mashing to try and wake it up if it's been asleep for a while, or when it's gone in to sleep/hibernation due to a low battery, plug it in, takes about a minute to wake back up, with the frustrated key mashing, trying to work out whether it's turning on or now... On my old laptop (other than the standard opening the screen again), just press the power button and on instantly all the time or press the power button just after you have plugged it in (after the battery died) and on instantly. If not at least it has a light to tell you it is working...

So yeah... Just works... Hmmm, questionable.
