lets look at this in another way..
The article makes some good points, but the argument can be turned on its head.
Why buy a $700 Apple device when a $100 android version will do 99% the same? And if the West's market is saturated with smart phones, where does that leave Apple? Trying to sell expensive hardware into a market like China and India which just cannot support that price point?
Of course Apple will survive, because as has been shown there is a value in the cachet of owning a Apple product, but can it still grow and maintain the same margins?
