Yes. It has been like that since the day iPhone was launched. Arguably the whole (modern) Smartphone Market history.
So I am kinda surprised to see some of the reaction here. And it was easy in the old days when iPhone was in Financial Segment with ASP and unit volume. Now it is hard to judge without those Data. And no where on the site do they mention how they calculated the profits.
Also worth mentioning Apple used to make 95%+ if not more than 100% profits because other vendors were losing money.
