Does anybody else think that the retina display will be MBP only for awhile before it makes its way to the Air? There are a few reasons why I'm pretty confident on this: 1. Cost. The MacBook Air has become the "average user" laptop ever since the white Macbook was dropped from the line. So, cost is a main priority for the Air, and retina displays cost more. 2. Battery life. Since the Air is so thin and light Apple would most likely be unable to keep the same battery life as the current gen. if a retina display is added into the mix. We saw this with the new iPad, which became heavier, hotter and slightly thicker. If the MBP loses the optical drive, Apple will be able to utilize that space for more battery power, but the MacBook Air has no new space to utilize. 3. Power. Even though Ivy Bridge is a decent leap forward, it is unlikely that Apple would be able to power a retina display while maintaining the same amount of "snappiness" of the current Air using a ULV Ivy Bridge chip with integrated graphics. And unlike the MBP, the Air probably won't be seeing dedicated graphics anytime soon. What do you think? Will Apple be able to overcome these obstacles, or will the retina display be absent from the next generation Air?
