Owning Apple gear signals status among a significant portion of the population. Maybe not for you, me or the majority of HN's clientele. But even for those who don't buy into this definition, adhering to it can still bring tactically social advantages.
I have a very hard time believing you're not aware of this, and feigning ignorance in order to criticize the fact is just disingenuous.
Then why did Apple lower the prices of iPhones, iPads, and MacBook Airs?
According to that link’s definition of a “Veblen” good, if Apple had raised prices, then demand would have increased. Either someone in charge of pricing Apple products missed out on huge revenue increases by failing to raise the price, or it’s not a Veblen good.
And there is no contention that the amortized cost of an iPhone SE, iPad Mini, or MacBook Air gets you the lowest cost to quality ratio of any competing product that also last the longest.
