NegativeZero said:By getting cozy with Samsung they likely get access to more than just an ARM-based processor. Samsung makes Hard Drives, Flash Memory, SDRAM, Smart Cards and LCDs. Getting more components from a single supplier reduces costs from a logistical perspective.
Additionally there's that rumor floating about that Apple are interested in the PDA/Portable market. Getting an ARM chip could well be a strong step towards that. They can use them in their iPods and everything, but they'd also be a very likely choice for a PDA processor. In fact, Apple used an ARM-derived chip in the Newton. You'll also see the ARM-derived XScale processor used in a myriad of modern handhelds such as the Blackberry and much of Palm's recent offerings.
You do know that the PortalPlayer chips are based on ARM architecture too, don't you? A PortalPlayer chip is a system-on-a-chip containing two ARM cores, SRAM memory and controller plus a DMA controller. This says nothing about Apple's future plans.
That said, I really really hope the new implementation would bring gapless MP3 playback with it. We've been waiting for too long dammit! Probably not though, since there's nothing in the PP chip that would prevent this even in current players...
