I think the kind of people who just look at the size of the screen and not the number of pixels, are likely the same people who will just buy the same size Windows PC because it's several hundred dollars less.

In other words, the people willing to pay Apple prices care enough about their computer purchase to actually read the specs. Like if you buy a high performance car, you at least want to do enough research not to look like a total idiot in front of your gear head friends after you've spent that much money.

Or maybe I'm wrong, and Apple customers really only care about how nice it will look on the coffee shop table.
