I get what your saying, but the Pro's are supposed to be better than the Air and Macbook in just about every feature. The big deal change to me is the higher resolution screen, standard SSD, and giving a slight implication optical drives is no more. So, if a 13 inch Air has 1440x900 would a 13 inch Pro have more? If they remove the optical, how much more battery or less weight will it be?
