I have a Rev.c MacBook Air (2.13Ghz) and after 6 months of use, the hinge moves about 6-10 degrees "freely" Basically, I can move it without feeling any tension from the spring. It used to never do this. I don't use a speck seethru case (that adds weight to the display)and no other cosmetic changes. Just normal 2-6 hour a day use. I think I read somewhere, at 35 degrees apple will fix it but my warranty is only 3 years. Will it get bad enough for apple to finally fix it? OR does apple cover this even if the warranty is out. It's prety obvious that the spring is getting weaker and the "bounce" while typing is getting very noticeable.
