Agree with everything written so far - brighter, clearer screen, with a narrower viewing angle. My old macbook screen had concentric rings of brightness from either the light source or a slight ripple in the screen, wasn't sure what. This one has a perfectly, beautifully even screen, more even than my last-edition macbook pro and my 20in cinema display - as long as you get the angle right! Otherwise it's negative blacks all over the place.
