Nobody will build a store/service network like Apple
Especially not Far-Eastern companies.
So, you'll always have to hand in the phone and hope it will actually arrive back.
Apple does repairs, too - but they also do walk-in full exchanges.
Of course, the (largest) iPhone 6S Plus is about five times more expensive than I would actually be comfortable to spend - there's no denying about that.
But at least, I'm the customer and not the product.
Apple doesn't use my data other than for themselves.
That said, the Watch has never appealed to me. First, I've already got a watch. Then, it doesn't look rugged enough for my sports (mountain-biking). And apart from the hr-monitor, it doesn't have any other features I would actually use (I don't read any of my main email-accounts on my phone, I pay almost always in cash, I don't receive a ton of notifications (deactivated most of them) and because I still own an iPhone 4S, I can remove the phone from my pocket and hold it with one hand when somebody calls...).
But the iPhone's value is still superior to me:
- single vendor for hardware and software
- walk-in support
- OS updates with no hassle, long support cycle
- hardware seems quite durable
- very secure (once you active Find My iPhone and give it an access-code, it's basically a brick to any thief)
- vendor has made a commitment to my privacy
If there was an option (in the form of a subscription) with Google so they would not track your behavior, mine your data and sell your information, place adds all over your screen etc - I would consider that.
But I suspect it would be even more expensive in the end than owning an iPhone.
