What do you mean exactly when you say that the iPhone "is a prestige phone", that it is "at the very highest end of the market", and you use this to explain the iPhone's popularity? Do you mean: 1. It's the most expensive smartphone? 2. It's the smartphone with the highest specs? 3. It's the most popular smartphone? (which would be a tautology... it's popular because it's popular) "Desirability" and "cachet" are outcomes, not first causes. To what cause are you ascribing the iPhone's success?
