I've seen the defect some MBA rev. B had with their screen. The "lines" affecting a lot of the screens of this revision of the air. But I have myself having the same issue but not on a MBA, my own Unibody Macbook. I've found this while I was playing under Boot Camp, and it is affecting the two OSes, so that's really an hardware issue. It's right there on the lower part of the screen. How did you deal with the issue, MBA users? Should I ask for a new screen? Does anybody got their screen repaired because of this issue? (My computer is already 3 months old and I've gone through a repair already, so no replacement for me).
