Using their weight, huh. Apple hit 10% market share with the Mac for the first time in 2012. I think it's something like 15% now.

And because they have a phone, they could totally ditch the cdrom, because, like, who wants to use a CD on their phone, right?
And the ethernet jack! Man, I felt stupid having to plug my phone into the wall for the internets.
But that headphone jack. Their phone totally blazed that trail, getting rid of that. Wait, what? The Macbook dropped it in 2015?
Surely though, most people that have an iphone use a mac right? That's the leverage point! Well no, only about 10% of iphone users had a mac in 2015. Even if it was 1-1, what difference would it make? There's no leverage to be had. iphones work with windows last I checked, and the growing trend is not bothering to "sync" your phone with a computer at all.
If the share was calculated by individual PC models and not by company, even in the PC business, there would be a bunch of Apple stuff ranking quite high.
So they can scale on many aspects much better than their competition. (plus they still have margins)
