You're funny... sorry if I used the term "scarcity" incorrectly... Nevertheless Speaking anecdotally, the discussion of shortage of <insert apple product> does create a whole lot of media coverage and excitement. Also known as free advertising... And Let's not forget that Apple products could probably be considered luxury goods...
Apple does build hype on purpose, they could pre-produce more products before launching, and ensure that all customers were serviced.
And I can speak from personal experience that I have impulse purchased several apple products in order to not have to wait longer as a result of comparison shopping, and returning to find limited stock sold out.
Maybe you're not a member of the target demographic?
No, I am. And see my above comment, I'm not trying to be condescending. Apple is GREAT at creating hype. But scarcity (in this discussion) isn't about hype, it's about a lack of product. They're doing all they can, but due to huge success, their demand far outweighs initial supply. It's just simple economics.
