I'm not sure its as good as the screens in the uMBP's but IMHO its definately a "step-up" from the original uMB screens.Computerworld reports that the new screens are similar to, if not exactly the same, as the screens found in the MacBook Air. Retail Apple Stores that have been checked seem to still have the original (worse screen) units on display.
