UPDATE: Apple finally fixed my apple air under warranty, if you have the same problem please quote my serial number W880634NY5. This way they can not tell you they do not fix this problem under warranty. Good luck, and please post your experience.
Apple macbook air has a defect hinge. After 10 months the hinge breaks. Apple does not cover hinges under warranty.
