UPDATE: I've just returned from two different Apple stores in my area. EVERY single MacBook Air had this issue, no matter if it's the 11" or the 13", or even Samsung panel or LG panel. I simply cannot believe why any company would let this quality of panel make it into production. I couldn't believe it until I saw it with my own eyes.
One thing I quickly noticed after browsing in Safari full-screen, there is a very apparent gradient effect at the bottom of the display. I've owned the 2010 Air and never noticed this bad of a viewing angle, so I'm unsure if the problem might only be with the new model.
I tried my best to photograph the issue. It's about a half an inch in height at the very bottom display.
Edit to other responders - the angle has nothing to do with this. It basically looks like a dithered drop shadow at the bottom of the screen. The op was just trying to capture it as bright straight into a lens won't often show defect.
