Don't be a troll...

Wow, people who buy 32gb and especially 64gb are not smart. They pay $100 or $200 more for same phone but extra memory only cost like $10. These peoples not good at math apparently and buy rip off model. Ha.


The only price difference in that BOM chart, if you bothered to properly assess it, was under the NAND FLASH material cost breakdown:
16GB = $19.20
32GB = $38.40
64GB = $76.80
Otherwise, all the other BOM line items are exactly the same price ($176.80) regardless of which capacity size is featured for the particular iPhone 4S model. And since you're presumably very good with math surely you've noticed how the above prices
doubles in cost as each memory capacity doubles in size, which is reasonable to expect BOM-wise. Therefore you have to pay a little more in general to get more pre-installed flash memory in the iPhone 4S.
But yes, Apple does charge more to preinstall larger HDD/SDD capacities into their systems, but, unlike say with the MacBook Pro, you can't just install extra storage capacity yourself into the iPhone and thus save a few bucks with 3rd party vendors, let alone upgrade it's capacity when you potentially need more space at a later point in time. So the $100 - $200 "value" for extra memory is subjective and is based on one's needs, both perceived and real. But to call those
"peoples" who want the extra memory as being
"not smart", especially as there is no other alternative to lower the consumer cost on that end, is just unnecessarily rude and prejudiced on your part and contributes nothing noteworthy to the discussion.
