bought the new Air on launch, its started to click from the seems on the bottom, normally when i picks it it or move it i can feel it click slightly.
any one else's doing this ?
Yep, mine also doing that kind of thing. Clicking, creaking, popping. There's already been a couple of threads around the forums here with people reporting the same issues. Some people took it to the Apple store and got their laptops replaced. Others got the screws tightened, which solved the problem.
I bought mine in Singapore and I live in Latvia, where we do not have a real Apple Store (just resellers). But we do have an Apple Service center, where I took my 13" ultimate MacBook Air to fix the problem. The technician re-seated the bottom case and it decreased the creaking sound, but did not completely remove it.
I bought a pentalobe screwdriver from ifixit, and tried to tighten the screws myself and messed them up (some don't turn anymore due to broken heads). Now I ordered an original replacement screw set through ebay and got a Macbook air 13" technician guide, which tells the exact order in which the screws should be put in (

The creaking sound drives me mad and makes me disappointed. And I feel a bit pissed off about having this kind of trouble with my first Mac.
