What a brouhaha. Apparently the people buying MacBook Pro's are so non-professional that they are duped into buying a machine with too little RAM? I think they get a 30 day return free, so if they find out they were duped, why not just upgrade. And while the upgrade cost may be extortionate compared to NewEgg, a 16Gb machine is just $200 more, still considerably cheaper than the same model was in the Intel days.
I suspect that people who have decided to pay extra for the Pro model may actually have some idea how much RAM they need.
