Maybe this whole thing was a subtle PR stunt designed to improve Apple's position in negotiations (as now you probably have the Account Executives in charge of Apple's relationship calling frantically and making concessions to keep Apple happy).
Or a "PR Stunt" to boost webhits at SemiAccurate?

The report at SemiAccurate links up to support stories at inquirer..... however all of the stuff is written by the same person.
Looking over at Dell's site appears to be quite a few boxes that have flipped over to i7. The causality of "bump problem made them dump" is very suspect for that shift. For the AMD and i7 ( and coming i5 and i3 ) the "blowback for bump problem" is a seriously flawed hypothesis.
If look for boxes with Core 2 Duos on Dell's site.... surprise you run into Nvidia products.
I'm sure the problems Nvidia had caused some negative impacts with their Apple relationship. However, seems overblown (unless Nvidia is truely incompetent. )
From a core I/O (with integrated graphics) chipset perspective since Nvidia and Intel are suing each other over Core i7,i5,i3 offerings , does it make any sense what so ever that Apple even remotely try to walk into the middle of that???? When Intel and Nvidia are done taking whacks at each other and the legal clouds clear then perhaps maybe Nvidia might have a chance. However, if Nvidia showed up with some dog-and-pony show that claimed they were going to win and to start incorporating their roadmap into Apple's future plans now. Yeah, that would be "don't call us, we'll call you" moment.
Similarly with the "Intel IGP is complete crap". Why would Intel put a complete crap IGP configuration inside the chip package with their latest, bleeding edge mobile cores (Arrandale)? Is it going to win performance benchmark contests against all comers? Probably not. Could it slightly less than double scores with a process shrink (from previous implemntations) and a few more graphics cores? Sure.
They can make people take IGP because it is bundled, but if th IGP sucks really badly then folks may not buy the whole package.
The average gap between Mac Pro updates about 6 months so conceptually since Arrandale is due in Q4 2009 and there is no January MacWorld show to hoild them back for could release new laptops in December. May have trouble getting major media attention, but possible.
