That’s even MORE true now since, as far as the Mac is concerned, Apple’s focused on folks that want/need macOS only. Apple’s fortunes are tied to how well they perform across the entire spectrum of goods and services they provide and the Mac hasn’t been a significant part of that equation for awhile.Quarterly numbers are interesting, but in the long run irrelevant (and heavily influenced by a number of volatile factors). The inherent Apple Silicon value proposition is just extremely solid, most of all in the laptop space. Fast + thin/light + long battery life, all at the same time, is a combination you just cannot get anywhere else. As long as that is the case, and solid regular, incremental updates are coming, the only way for AS is up.
That being said, Apple will probably never be #1 in the PC space wrt to unit sales, simply because they‘re not willing to hit the low to very-low prive points that would be necessary to have a shot at this. From a profit point of view, it‘s absolutely the right strategy, too.
Regarding unit sales, Apple has been in the top 5 and, in many years, have beat the unit sales of the entire line of laptops made by every other individual manufacturer… with the iPad.
