What is your opinion on this?
There is no point of just upgrading the RAM itself, that alone won't get the attention of more tech savvy users, and for the non-tech savvy consumers, there would be no grasping point for Apple. You would have to have something else that captivates them in terms of functionality. From my experience, 4 out of 5 consumers won't give a hoot about the RAM upgrade. If you, however, say it runs faster because it has a better processor, they would at least recognize "faster" and "runs better".
