@Terry well, to make an iphone, you have to have gorilla glass, so you have to buy at least a million gorillas
and of course a gorilla masher, or two if you want multi-threading
and there's a chip in there, i've been to the grocery store, Doritos are like $6.99 a bag, but there are a bunch of chips in the bag, so that's a relative bargain
batteries require a lot of rare earth minerals, so you have to dig where the earth is rare, and that means (for the US) in Hawaii, which is expensive because they believe in volcano gods and will kill you
so i think $100K per iphone is probably on the low end tbh
