It seems like the revision C screens' max brightness is dimmer than prior ones? Am I smoking something? Are they still 300 nits, no matter which actual panel you get? What about revision B's screens? Are they at least 300 nits? I was comparing the MBA revision C screen to the new macbook plastic screen and it did not seem as bright. It was obvious. I remember there was one 13" mbp panel that was not 300 nits as well, and it looked not as bright as I'd been accustomed to.
