Apple was always about FUD or making ridiculous marketing claims. I recall how in 1998, when they came up with the G3 PowerPC based computers, they were making the ridiculous claim that 233MHz G3 in an iMac was faster than 400MHz Pentium II, even though the claims were not based on some real world usage experience or benchmarks like spec int, but on some obscure Photoshop based benchmark if I recall that correctly. By the time Apple started using the G4 processors, claiming to be faster than Intel was not enough. Now they claimed that G4 is a supercomputer processor. Then couple of years later they announce the switch-over to Intel.. surprise surprise.
Granted, in the more recent times Apple hardware has usually been top notch, but companies will always have a need to spread marketing FUD against the competitor products..
