Yep. My daughter has the earlier iPhone 5 and hates the update because it broke working things. Important things, not nuisance stuff.
The meme is that Apple is fast to update and everyone gets it.
The truth is that it *always* takes some serious update cycles before you really have the goods on any of their major revision changes.
That's just how they've rolled with all of their stuff since OS X 10.2, roughly ten or more years ago.
Informed Apple consumers expect it and weather the storm patiently.
The Kool Aide drinkers freak out when it happens to them, but because there's no magic, just a business practice, we see the outcry and infighting every time.
It's past boring because it's so predictable.
