For years Apple has been adamint that just because the P4 had a higher MHz, that didnt mean it is better. Now that APple has announced that they are switching to the P4, what happens to the MHz Myth? I would assume they wouldnt do this unless they have tested it significantly and can prove that the switch is benificial. On MacRumorsLive it says "Every release of OS has been compiled for intel x86 for the last 5 years - cross platform by design." THat leads me to beleive that the switch should be seemless. Any thoughts?
