"It's better to keep fast charging an optional accessory for the few people who actually want it"
It's a fact including something in the box will see more people will use it than not including it. I'm paying the same $1000, it should be in the box like the competition. fukk all the less for more shyts, no reason a 2017 or 2018 Apple flagship shouldn't come with what's standard on mid range or Android flagships.
