This all comes back to the old “market share” argument. Apple has never really strived to have the largest market share for any of their devices (the iPad is an exception, if only because it essentially defined the market and it’s taking time for competitors to poach them down to a minority position) - they’re typically aiming for about 30% share or so.
But that 30% they’re targeting is where the majority of the profit is, on the higher-end side of the spectrum and potential customers who are willing to spend money. Note that despite having about a 20% market share in the smartphone market, Apple pulls in a majority of the profits. That’s their business model, and to date it seems to work for them, even if it annoys Wall Street.
By the same token, people who own iPhones and iPads have consistently been shown to use their devices more than those who own competitors’ devices. In that respect, there’s nothing unusual about this particular finding - it merely confers previous results.
We all know Apple likes to mine the elite sectors of urbanites, urban gays, Subabru drivers and hipsters etc. Having said this, they can F off. I have more respect for a company like LG, Lenovo or Samsung or HTC that brings products (smartFones, tablets) to the world (such as in Uruguay and Thailand) not focusing on the self indulgent elites of certain developed nations.
This arrogance is going to backfire on Apple being they are ignoring vast segments worldwide who would be thrilled (due to media brainwashing) to buy Apple fones tablets at lower price points. Others I have mentioned are rushing in to fill this demand. Thus penetrating the mind of consumers in ways that they will never be buying an apple gizmo. Samsung is already achieving lift-off on this in America, other developed nations and second tier nations like an Argentina and India
