Unfortunately I think Apple has reached its peak......
It is only their phone that helps keep them ahead of the tech world. Everything else they put out has flopped except for the iPhones which is still going strong. Because Apple knows this they keep marking up their phones and eventually this will be their downfall.
Sadly, the only way they can profit now is just from their phones which is in my opinion too high for any phone that is $1000. They are losing the market for the middle class.
