Food for thought: Intel once made one of the fastest ARM chips ever, the StrongArm (later called XScale), before selling it off to Marvell.
One of the architects of that chip? Dan Dobberpuhl, who later started PA Semiconductor, which was afterwards bought by Apple.
So many of Apple's ARM team were once designing ARM chips for Intel.
@hm: it may be too premature to declare the "success" of Thunderbolt high speed interconnect. Apple has had a history of going it alone throughout its corporate history; the only differentiators this time are the much higher volume consumer devices (as opposed to desktops of the past where Apple received a drubbing!). Apple also makes it easier for others to fill in the gaps it doesn't serve (read: flash-capable devices, for one!).
I don't believe Intel is going after Apple's foundry business entirely for revenue reason (there are TSMC's, UMC's of the world for lower costs for that). I think Intel sees an opportunity for technology collaborations for its next generation of Silicon.

Apple is moving in the direction of rivalary with an old friend. I think it's the inner fear of Android and also the fact that Smamsung keeps it's profit margins lower and thus can outperform Apple any time!!!
This gives too much to Intel, in return for what exactly? I am not sure Apple should go down this road. They should stick with the well-known and trusted pure foundries. Granted the tie-up with Samsung is problematic but a tie-up with Intel would open up more and bigger problems in the future.
Once again, EE Times readers have offered a lot of valuable opinion and reasonable speculation. Let me just add a couple points briefly even if they have been alluded to previously. Moving to Intel as a foundry does not mean moving from ARM to X86. It could be further down the road and be something proprietary developed (or acquired) by Apple. Also, Intel has lots of motivation to take on Apple business, not least of which might be staving off a surging Samsung who have long set their sights on being the world #1 semiconductor company.
