Poor people aren’t buying iPhones. People spend $1000 on these things. They can spend $1000 on a mac with an arm chip too. And even if some don’t, you have to rule out a lot of people before 820 million becomes less than 80 million. Again, simple math - apple sells 300 or 400 million iPhones a year, at around $800 a pop. They sell around 20 million macs a year at around, what, $1300 a pop? If they can get some of those people who buy iPhones to also buy macs, its pretty easy to make up for closeted windows users who will be offended and not buy another mac (which they probably weren’t going to do anyway).
You didn’t believe when i told you iPhones blow away macs in terms of number of devices, that the number of iPhone users blows away the number of boot camp users, etc. I cite actual numbers, and now you change the argument to “hand wave hand wave iPhones are dual purpose those people wont buy macs hand wave hand wave.”
Give it up. Apple is aware of the math. They see the iPhone halo. They know that they can sell macs to iPhone users far more easily than they can sell them to windows users. That they can’t easily differentiate macs to be desirable to windows users, most of who are happy with dell or acer or whatever MacBook clone comes around at a much lower price. But they can sell macs to iPhone users and if they control the cpu they can control the features and integrate it with the OS in ways that the competition cannot.
