Just because you can't see the problem, does not mean its not occurring, I just received mine last night and the lines are there-similar to the earlier powerbook image but fainter. I don't find the lines to be the issue so much as what seems to be the result-fuzzy characters and images. When compared side by side with my first gen. blk macbook the screen on the mba is brighter, has more contrast etc. but is not as sharp- For a premium product- this is not acceptable. I was told last night on the support line that it is within spec. Not sure what to do now as I like the size and it seems like people that see a problem aren't getting results.
