The 32GB iphone 4S is only 11 dollars higher than the 16GB version.

IPhone1 Month 9th News, according to foreign media reports, 16GB version of the iphone 4S and 32GB version of the difference between the 16GB NAND flash, consumers spent more than 100 dollars. But Toni Sacconaghi, an analyst at Bernstein Research at the institute, said Apple could buy the flash memory at a very good price (USD 0.67 g), which would cost $10.72 for the extra 16GB purchases. Obviously, this is a very lucrative strategy, and Sacconaghi believes that NAND one has made Apple a bonanza. In the fourth quarter of 2011, the industry expects Apple operating profit of about 2.2 billion U.S. dollars, gross margin of 78%, thanks to the larger volume of Apple products, of which the majority of profits from the iphone, which other OEMs have not yet emulated the strategy. Ironically, Apple earns nearly twice times as much from resale NAND flash as the sum of other NAND suppliers ' profits. Last quarter, the resale of NAND sales accounted for 20% of Apple's operating profit, up to $10 billion a year. By contrast, Android phones such as Samsung Galaxy S2 have only one capacity, and support for expansion is good for consumers, but not for manufacturers.
