If in the Glenn Ford bitchslap picture above (lmao, btw) you can't differentiate the brunette's hair from the black background, it's a crap screen. When your friend fires up his $200 netbook next to your macbook, and you think 'Holy crap, that display's gorgeous!', likewise. When it's painful to watch a black and white movie on your $1300 or $1700 portable, you know that Apple screwed you. When Apple itself quietly updates the screen without telling anybody, it's a good sign that they admitted (at least to themselves) that they made a mistake.
Honestly, there are some people who will defend every decision that apple makes, period. They would rejoice and dance if Steve Jobs dropped his trousers from on high and pi$$ed on their heads.
OTOH, if you're display was working just fine for you, and you decided you wanted to replace it just because you heard the newer ones were better, then to heck with you. My 9c8c is acceptable as well-though the contrast is better on my powerbook!
