It's possible - but (using me as example who has a great screen) I have seen the screen shots people have posted and I can see the lines in the photos - and then I see threads where people ay no, you have to tilt your monitor 45 degrees, or from the side etc etc.... and after a while it is silly. I (for example) cannot see any lines - and I have 20/20 vision. I use my monitor straight on from about 2 or 3 feet.
Thanks, though I'm sure you're right it would be great to have some objective way to poll this. E.g. would be nice to have a definitive number that X% of the screens are bad and (1-X)% are not.
The fact that yours is fine makes me hope that around the time of Macworld these problems will be sorted out, cause that's when I plan to purchase one. And I definitely wouldn't do it given the current uncertain situation.
What really boggles my mind is that in this case very few people actually are annoyed enough by the problem to return their laptop to Apple within the first two weeks or at least have Apple Care try to fix it. I remember e.g. when the MBP's first came out and had this logic board whine everybody would send their in and some got fixed, some didn't. However here it seems people are in this sad state of acceptance of the problem, as if that's just the MB Air God wanted them to have.
