Has Apple ever done that ? Years ago Apple had a massive marketing campaign built around trying to "teach" people that you couldn't compare PPC GHz with X86 GHz, and on the whole it was a bit of a flop and people just went on assuming that a 2.5GHz processor was faster than a 2GHz processor. I guess they learnt their lesson and instead of trying to convince people that smaller numbers actually sometimes are better than big numbers, they now just never mention the smaller number.
