That's a bit of a stretch. The early iPhones 'just worked'. My Mac used to 'just work'. All was groovy in my Apple life as 'recent' as ~2011.
I wouldn't say my Mac 'just works' anymore, nor my iPhone for that matter. And this is commented on a lot by a lot of prominent Apple bloggers, to the point that it does get responded to by Apple SVPs (see Marco Arment and Phil Schiller)
EDIT: that said, my mum gave up the PC when she got an iPad 2, and was even happier when she got a hand-me-down iPhone 4S. She finds both slow now, but still won't go near the PC anymore. For her, the Apples still 'just work'.
