Help MBA Black Plastic Hinge Cover Noise

[pegman]

I just got a 13" MBA last week and noticed that the black plastic hinge cover moves a bit and makes noise when I push it lightly. It also rattles when the fan blows hard. I took it to the Genius Bar but they said that the hinge cover is designed that way. I checked a few demonstration units and they didn't seem to have the same amount of play. Is this normal?

I had a similar problem (minus rattling from the fans) on my previous MBP and the one recently purchased. Suppose this is normal.
