Ok, I'm a bit confused here; Business Week's guys may have a better idea what they're doing but not two weeks ago ZDNet runs
this article saying that even with a below-going-rate discount on flash memory, Apple's pratically selling the Nano at a loss, and for the flash memory to be as cheap as iSuppli is saying, Samsung would have to be selling Apple flash storage almost at a loss.
The ZDNet claims Samsung is selling wholesale flash storage at $45/GB, and that's a 45% markup. That equals $49.50 per 2GB just to manufacture, where iSuppli is claiming Apple's getting the stuff for $54; that would mean a 9% markup over cost, which is viciously thin no matter how you look at it--would Samsung really be willing to go that low?
Of course, you can also look at
this article, which is claiming that the Nano is so cheap it's seriously cheesing off Korean flash-based-player manufacturers, since there's no way they can match the price, and
this article which is saying that other players in the Taiwanese market have had their prices slashed to compete. So even if Apple's margins are a little large, they're certainly not out of synch with the rest of the market--if anything, it's cheap, though that may be because Apple is letting Samsung take all the pain.
Worth noting that ZDN implies the Mini has margins in the same percentage region as BW is saying the Nano does, so even if correct there'd be little change from before. And also worth remembering that that's just the margin over manufacturing cost Apple does; in their last quarter Apple made about 9% profit on their gross income, which is a little high but not terribly unreasonable. Contrast with Microsoft, who made a 26.5% profit in the same quarter, even with their money-loosing divisons.
