I have heard here and there that the glossy screen on the MBP's isn't all that Apple would like you to think it would be. Currently, I do all my PP work on a 15" 1GHz PB G4 AI and only have issues in broad daylight for clarity/legibility. It gets calibrated often, and I've learned to anticipate color shifts from my lab on most of the images I capture. What with the PB being long in the tooth, I'd like to upgrade to an MBP, but need to know about the screen differences. There's not really a nearby Apple Store, and I don't really trust the floor models anyway, so is there someone out there who does photography professionally/semi-professionally with a solid opinion on screens?
