After reading a lot about the degrading screen quality between the Unibody Macbook Pros and their predecessors, is the Unibody's screen really that bad? Honestly, I could not tell the difference in the Apple store, just that the older MBP was slightly more dim because of the matte coating, but is that all? A matte coating and lots of biased people?
