I had my bottom case tightened earlier today. From the looks of it, the screws might have been stripped/rounded by the Genius. Can you guys confirm?:
Same picture but zoomed in. A little blurry though:
Or should I not bother to worry about this because it is meant to be non-user serviceable? It just irritates me that it is a brand new machine now with possibly stripped screws of which none of the Apple stores have replacement on hand. On the side note, no creaking now. Pardon my OCD but I'm expecting a premium product with no defects considering we paid a premium price.
