When you see the brightness comparison you'll be amazed. Not worth getting rid of the PB for the MBP just for the brightness.. its not THAT amazing, but it is sweet... oh so sweet.
As for the glossy coating like you see for many PC Laptps, nope none of that. Regular matte like the PB. I guess Apple follows the saying "If its not broke, Dont fix it".
oh and the 17inch PB is thinner than the MBP. but the 15" and 12" PB's are thicker then the MBP
