After 9 days with my Macbook Air I’ve returned to the shop to ask for a replacement.

I noticed a few dark pencil thin marks appearing on the trackpad button and just wiped them away with my thumb. But they kept reappearing in the same place and getting more and more visible and also creeping onto the palm rest area too.

The marks are being caused by the top edge of the screen surround / bezel scratching the lower trackpad and palm rest areas when the case is closed and there appears to be a noticeable mark appearing on the edge of the bezel too.

I have also noticed that my trackpad button isn’t level in the case, the left edge sits lower than the right edge and consequently the right edge is getting more damage from the screen than the left.

My local Apple reseller have asked me to return the unit with box and all the bits on Monday when the area manager is around, I hope for a complete replacement considering the machine is 9 days old today.

I’ve had a quick search on the web and there doesn’t seem to be anybody else reporting this fault so hopefully its just a one off faulty unit and not a design fault across the Macbook Air range.

UPDATE (3rd March 2008):
I have just had my Macbook Air replaced without any questions. Becuase it was less than 2weeks old they were able to return it to Apple as DOA (Dead on Arrival) and issued me with a new MBA on the spot. I’ve not opened the new one yet but will be sure to report back here if the same thing happens with the replacement.
