Everyone waiting on the Core 2 Duo MacBook needs to get a clue.
It's the same folks who were falling over waiting to WWDC to come so they could order their Core 2 Duo MacBooks after the keynote!
Apple IS NOT going to move the MacBook to a Core 2 Duo until they've updated:
1) MacBook Pro
2) iMac
3) Maybe even Mac Mini, since it's been out forever!
The MacBook is barely three months old. It may get a speed bump and/or price cut soon, but won't get a new chip.
All of you saying Apple has to upgrade it to a Core 2 Duo to complete with Dell, HP, etc - why? Why do they HAVE to? Will they explode if they don't? Will the sun stop shining? Will all the world's puppies die?
Of course they'll upgrade it eventually. That doesn't mean it needs to be upgraded as soon as the chips are available. If you look at other PC maker's sites, most of their machines don't even have the Core Duo chips yet; there's no rush.
You can't claim Apple will inevitable act a certain way now that they're on Intel chips; you don't know that. They have no history of using Intel chips. Just because your bright minds think it would be a good idea to move the MB line to the latest and greatest chip whenever a new one is released by Intel because "that's what the other guys are doing," it doesn't mean Apple agrees with you.
What we DO know for a fact is Apple like to differentiate between consumer and pro lines, and Apple has never been one to put the latest chips into the iMac or Mac Mini level machines - and I don't see either of that changing.
