Perhaps I was being unclear- I don't doubt that they sold a ton of them. The length of time since the previous update alone would ensure pent-up demand.
What I don't think they did is sell many to developers or programmers. Although small in number compared to the overall size of the market, Apple's losses there are important. Mindshare matters when you're talking about the people you expect to build the software for the platform you sell.
Not true on Apple selling a record amount of Macs. Apparently they added 7 days to the quarter versus a year before and therefore Mac sales declined again. For 2016 Mac sales also declined compared to 2015. Apple Mac sales declining is tied to the lack of new OS X software, IMO. Otherwise why decline?
The HN echo chamber is strong, but its silly anecdotes don't reflect reality.
