@baldur Apple is the only company that does report sales numbers so they may as well quit. They aren’t particularly useful. Revenue and margin are better indicators how they are performing.
They may well keep the old low-end Air around so they can say they have a $1000 laptop, but I still doubt very much that’s what “everyone” will buy. Apple’s demographic are not particularly price-conscious. I think this has been demonstrated over the years beyond a shadow of a doubt. Even as a struggling student who needed a laptop, I never bought an entry-level model if 1-200 more got me significantly better performance and capabilities.
Not to say I am immune to price, as much as I admire them, Apple’s watches are too pricey for me. But I have been an Apple loyalist for ages because of the quality.
