Color accuracy, display evenness and grayscale viewing are all noted as excellent; the only sore spots are viewing angle and the grating lack of matte screen options for anything but the 17" top model. He notes that TechRestore may begin offering matte-screen replacements for the smaller units soon, for those who can't tolerate the glossy glare.
Not everyone is satisfied with the MBP screens, however. Designer Louie Mantia of the Iconfactory has a bone to pick with the screen quality of his new 13" unit; it's sporting a 6-bit display, which has been an issue with color-sensitive professionals for years now. To add insult to injury, the Apple store sold Louie the wrong DisplayPort adapter for his external display, and nobody at Apple HQ is willing to give him an answer on whether or not an 8-bit panel is even an option (hint: it's not, sorry about that). One could argue, as he does, that a 'Pro' machine ought to have a professional-quality panel... but that campaign's not likely to get much traction in the halls of Cupertino.
Apple has released Pro Applications Update 2008-04, which includes updates to Final Cut Pro, Compressor, Color, DVD Studio Pro, Cinema Tools, Motion, Soundtrack Pro and Shake. The update, according to Apple, "addresses general performance issues and improves overall stability."
