Yeah, but since the average Mac costs >3x the average iPad, we're still talking about 2-3x the number of iPad sales as Mac sales

The OP was referring to dollar sales, not unit sales.

Apple no longer announces unit sales. In any case, it has always been true that Mac Average Selling Price is much higher than iPad Average Selling Price. In the sense of unit sales, iPad is bigger than Mac and has been for many years, so in that respect the 2024 Q4 results would not prove anything new.

The OP was giving a false narrative about future growth that is contrary to what recent quarterly results have shown.
