Hi, I'm nearing the end of the two-week return period for my Rev. A refurbished Macbook Air, and am concerned about uneven backlighting. I spoke to a genius about the problem. She was nice about it, but said the machine was within spec. Another genius she spoke with offered to replace the screen, but couldn't guarantee I'd get anything better. To their credit, however, it was hard to notice the problem beneath the store's lighting. Check out the photos below. In your opinion, is my backlighting abnormal or within specification? I'm planning to return it due to the backlighting regardless, but am concerned/disappointed with Apple's opinion of quality if the machine is within spec. Thanks for your opinion.
