The issue for GBs is value to the consumer, not cost of components. It's Apple's form of price discrimination. Everyone else does get away with price discrimination in one form or another. Apple uses a simple and straightforward type which I think is a positive thing, even though it ends up connecting significant price changes to small component changes. Also if you look at the % more you pay over 2 years for more GBs, it isn't that bad since the contract price is way higher than the phone or GB upgrade prices. (Even looking at the unsubsidized phone prices, the increased cost for more GBs is a lower %. Subsidizing each phone model for the same approx $450 in the US makes the GB upgrade price differences seem larger).
