We all know local TSA units will arbitrarily make their own policy. With that said, simple question:

Does TSA allow a 13" Macbook Air (not the 11", the 13") through security without taking it out of your bag?

Bonus round:

• Does TSA allow the new 15" Macbook Pro with Retina display (the one with flash memory and no DVD drive, so no moving parts) through security without taking it our of the bag?
• International standards - do other countries' security firms follow a similar policy? What country?

Thanks. I'd make this a poll (yes or no) if I knew how.
