I bought the new slim 27" iMac back in March and I immediately noticed this when unboxing. It looks like streaks/residue on the outside of the glass but no amount of iklear or Windex will take it off (it's not in the outside). I had originally assumed it was just all the new adhesive people were talking about with these machines and that it wasn't full cured. Thought it might take a few weeks to settle. Well, it's now been 3-4 months and it's there as bad as ever. Does anyone else have this problem? I almost forgot about it because when the machine is on you don't notice at all, just when it's off. Looks hidious and I'm afraid it may hurt me when I go to sell sometime down the road. http://cl.ly/image/3j2H080U433X Sorry, best pic I could get with the glass screen there. Imagine this tenfold in terms of visibility.
