Comparing Apple only to the manufacturers who had to deal with those two giant monopsonies who supplied the two basic requirements for a "Wintel" PC is missing the point massively.
It also makes things interesting for this time around as Google and ARM have very different business strategies than Windows and Intel did at that time.
Somebody correct me if I'm wrong: hasn't Apple seen its Mac line market share grow for something like 26 straight quarters? And, since they're high-end / premium devices (> $1,000), the margins (and therefore profit) are higher (again, like iPhone).

This is more than the top 5 Windows vendors combined, and about as much all Windows vendors combined.
Microsoft on the other hand (though interestingly they actually made an overall loss that quarter as they wrote of a 7 Billion company they purchased a few years before) made about 4 bilion revenue and maybe 2-3 Billion profit from consumer Windows sales directly and that's not counting servers, or business licences, or Office each of which is roughly of the same magnitude.
Intel's PC client group took in 8.5 Billion that quarter. Possibly half of that being profit (overall gross margin was 58%.)
So Apple makes a lot of money from PCs, Microsoft and Intel have always made more.
Note that from selling iPhones and iPads Apple recently made more profit than Microsoft, Intel and a few others combined. But for desktop and laptops, Microsoft and Intel have always claimed the vast share of industry profits unless you go out of your way to exclude these two companies from the industry.
