>In the early days of the Apple/Intel partnership, their use represented something of a “pressure valve” on processor limitations that the Power Mac G5 created for Apple’s processor line. It helped solve a plateau in Apple’s laptops, which weren’t able to take advantage of the 64-bit architecture that the PowerPC G5 had promised to consumers.

I doubt Apple will ever forgive Intel for missing the Merom release date...forcing Apple to support 32bit for an extra decade.
