Also, the point about consumers not caring is a tad untrue. I remember that during the PPC days, many people would look at the CPU speed and think that Macs were "twice as slow." This was usually because a G4 @ 1.33GHZ seemed to be slower than an Intel/AMD @ 2.6+GHZ. Even though this wasn't accurate, it created a mental block for a lot of people. Intel gives people a level comparison, which makes Macs look much more competitive.
Yeah, this is true. Remember how much time Apple used to campaign about the "megahertz myth?" It was a staple in their argument when trying to get people to switch. When's the last time you heard Jobs (or anyone) mention the MM these days? Let's face it. They're grateful for the leveled playing field.
