of course Apple are using a different benchmark.
MobileMark 2007 requires Windows. I don't see Apple releasing official numbers that relate to Windows use and not OS X use.

Another possible plus: people with pacemakers may finally be able to undergo MRI.
My understanding was that the strong and fast-changing magnetic field caused current to flow through the electrode in the patient's body. Current translates to heat (not good...). Maybe if the field will be weaker this unpleasant(!?) side effect would be alleviated.
