"Better" doesn't exist in a vacuum. The question is always: better for what?
The majority of people who complained about the Retina MacBook are the people who either want or have a MacBook Pro. And, the reason is they want the Retina MacBook to be an upgrade to the MacBook Pro. The issue is it is not. My point is those people assume that the Retina MacBook should be an upgrade for the MacBook Pro line of laptops but it is not. Therefore they are upset.
