Not sure I follow the legal logic. The phone also doesn't work if you don't have a service plan, so does Apple have to include one of those in the box too? Come to think of it the power adapter won't be much use without a wall plug to plug it in, so is a house or apartment included? I'm exaggerating for effect, but what is the exact legal definition of what is married to the phone and what is just other stuff that you're expected to provide yourself, and at this point (phone "series 12" remember) why isn't a charger one of them?
What if I buy a drill bit, does it have to come with a drill?
