Earlier quoted context omitted.
It doesn't cost $450 to make an iPhone. That's insane. It may cost that in parts, but there are many, many highly paid engineers, designers, product managers, etc. who worked on those products. Those people's salaries must be accounted for somehow. This is something that a commenter on Hacker News should understand! All of those dumb cost breakdowns for what it "costs" to make iPhones or whatever always miss the fact…
The $450 is the marginal cost of an iPhone. That's typically the normal number cited for the "manufacturing cost" of a product, regardless of the level of R&D and marketing that goes into it.
GP also said to cover cost of app store in the phone, despite only costing its parts.
I consider iOS to be one of the iPhone's parts. I don't understand why machinery engineered from metal is so different from that engineered from bits, that I must consider them two products instead of one. Metal, glass, silicon, bits: one PDA appliance.
