Oh god.. Chi Mei sounds like a very cheap brand. It is a brand that is so very... east Asian sounding. How can you tell which panel you got in your MBP without stripping it apart?
I'm curious as to why you would say that? Based on the specs, the CMO product is superior to either AUO or Samsung.

AUO seems like a new addition since I don't think it was used in the original MBPs, but this would be the model Apple's likely using:

Clearly from the specs, the CMO product is lightest, and the most power efficient. It also has wider viewing angles than the Samsung. The only model with an advantage over the CMO is the AUO one which has a lower 16ms response time vs. 25ms for Samsung and CMO, but the AMO product sacrifices contrast ratio, only 400:1 compared to 500:1 for the others, and consumes 30% more power. I'm looking to get a new C2D MBP and personally I'm hoping to get a CMO screen.
The only way I know of to get information on the screen is to go SysPref/Displays/Color/Color LCD/Open profile/#13 "mmod". If someone can decode the manufacturer's ID number and the part number that would actually say what the information their means. Supposedly model 00009C56 is made by Samsung, but that's all I know.
