    I have the rev. C Air, recently bought. It works fine but I have noticed that when I tilt the screen back almost all of the way that the front left side lifts slightly off the desk. I can see that the front left pad is not touching the desk. Is this an idiosyncrasy of the computer? Do others have the same symptom? Of course once I place my hands on the computer and start typing it's not really a problem, but I can certainly feel it click down to the desk or if I lift my hands off and slightly push down there is a space there. I think it is a weight issue, because once I pull the screen slightly towards me the space disappears as well as the issue.

    YOu could try bringing it back for a refund if it bothers you.

    I don't have the issues, but there are other minor things that I've lived with...

    Can't bring it back.

    I bought it from a second party, though new in the box. It's guaranteed by apple, but from six months ago. From reading all of the potential pitfalls, this is relatively minor. The screen seems fine and the computer, so far, works flawlessly, though under heavier usage starts heating up pretty fast.
    thanks

    this is discussed in Macbook Pro area on this site

    ... more thoroughly. Bottom line seemed to be.... take it back within the 14 days.

    Or, with a little ultrafing sandpaper... (the white kind where you can't even see the bits) tweak one of the rubber feet a tiny bit, to get all 4 feet on the table at once.

    Or, perhaps just wait. Rubber feet are soft, and will wear down over time. 3 of them may wear down to where the 4th does start contacting the table.

    But this raises questions about quality control. Why would a carved aluminum slab warp? Especially a few, out of many? Not that this happened in your case... but any material has limited strength.... so if for example it were stored in a way with other heavy items pushing on it in an asymmetrical manner (as perhaps in a suitcase?)... over time those forces could warp it. Wood, metal, stone... they all can warp.

    But if it happens "new" I'd guess that the possibilities to explore would include..... (1.) that particular aluminum slab had some untypical tension in it. Perhaps there's some way to tighten up the fabrication of the blank slabs that then get CNC carved. Or (2.) perhaps they need to spot these rare warped ones after they get carved. Or (3) perhaps this is a matter of excessively big tolerances in the CNC router machine tool? I think I see a bit of that in the photo, around one of the jack openings. Whatever it is, and whatever the solution is... sounds like a case for Apple's new V.P. for Quality Control!

    My brand new MBP is doing the exact same thing. Apple is exchanging it for a new one.

    This happened with a few Macbook Airs I had, and I think it went away after a week or so.

    I went to a local Apple Store here in Prague, where I am visiting, and their Macbook Air also was a little off the desktop as well with the screen all the way back. Whe you simply tapped on the trackpad, yo could feel the slight play between the front pads and the desk. It seemed even worse than mine. The salesman looked at me as if I was a bit oversensitive, then took the machine in his hands and started bending it, almost brutally. He put it down and it was a little better but not completely. I would never try this at home.
    He suggested that I call Apple Support if I wanted it looked at, but given that the one in the store was much worse, and that mine is not nearly so bad, I would worry about Apple fiddling with this. It's not as if you feel it click down when you type or rest your hands on it, it's just when you lightly tap the trackpad (I only use tap to click) that you hear the slight click of the space.
    We'll see over the next few weeks if the pads eventually even out.
    Thanks for all of the advice.

    Mine does this I think its probably cause by heat warping it / lack of weight on that side.
