Manila folder for MacBook Air

I have a fairly new MacBook but that doesn't stop me from lusting after the new MacBook Air, Apple's, nay, the world's thinnest laptop. And with that, I'd like to buy the AirMail manila folder to tote it around town. How cool would it be to show up on my first day of law school and pull this slim beauty out of what appears to be an ordinary manila folder but is actually a fleece-lined laptop sleeve. (Answer: So cool.)
