"It's not hard to conceive of a new machine equipped with Intel's latest 'Arrandale' Core processors - the ones with graphics and memory controller modules built into the CPU package."
It's very very easy to conceive of such- MacOSX benefits hugely from a proper GPU these days, so I'd rather avoid anything using another horrid Intel abomination pretending to be video hardware. It might be better than the 945 stuff that I am used to in my Netbook, but really, truly, compared to the pair of NVidia chips in my MBP? Driving a large-ish, hi-res-ish screen like that with Intel video hardware would mostly likely not be very nice.
Ok, so that's a baseless prediction, but what's the worst that can happen? I'll be proved completely wrong, and Intel will make some video hardware which doesn't blow goats? I suppose it could happen, in theory...
