Hmm, the MacPro with the Xeon 5500/5300 was on the market approx a month before the other vendors. Similarly how is this page:
http://www.apple.com/macpro/features/processor.html
not an advertisement for Intel. 'Intel' appears 7 times and there is a direct link to the intel website.
No apple doesn't talk specific CPU model numbers. Specific CPU model numbers don't build overall corporate brand awareness.
You can bet that when Apple introduces the i3/i5/i7 version of the laptops that will be at least a couple paragraphs if not a whole web page devoted to how "insanely great" it is that Intel (not AMD or anybody else) merged the CPU and most of the formerly classic northbridge onto one package. It will be battery life / power savings / better Stream, office application, 2D graphics , etc. benchmarks / something.
Likewise Apple currently running 9400m up and down almost its entire lineup is beneficial to Intel? No. If Intel wipes that out .... there is no upside for Intel in that?
EFI .... developed by Intel and implemented across the line up by Apple. Who else has done that? (sure Apple isn't unhappy that folks didn't follow along with that. )
Sure Apple lags on adoption of the "Extreme" and high thermal versions of the mainstream chip lines. Likewise doesn't peddle the VT crippled ones nor the Atom stuff. (although folks speculated they'd use Atom over and over again. Go back and look at any Pine Trail announcement here on macrumors. ). Nor does Apple put those tacky stickers on their products. However, Apple puts Intel's overall brand name out there over and over again in several major announcements. Much better than the days when running ads about how their products are snails or the possible alternative universe where that MacPro page extolds the virtues of Opteron. (effectively very similar arch benefits )
Apple has a relatively smaller product line up that other vendors their size. They also have a more spread out product release cycle ( goes with having fewer, non-overlapping products). So the opportunities to synchronize an Apple hype cycle with an Intel one is fewer. Doesn't mean they don't exist.
The laptops all got refreshed relatively close to before the mobile i3/i5/i7 product release came. They are a bit out of synch and so Apple will be rolling out after instead of before. Apple isn't going to bend over backwards to promote Intel; just when it is convenient and synergistic.
