Get a refund for now. It's a hardware issue that may not be resolved right away....It looks like all week 43, 44, and 45 models are exhibiting this, or 95% at least based on the forum findings and the people checking in the apple stores.
I have a week 45 model and have the same problem with the lines on the screen.
I had it delivered to my office and noticed the lines as soon as I had the OS booted. It had been bugging me all day at work, I assumed that my MacBook at home would be the same and I had perhaps just got used to it. It's not, it's much clearer and just as bright (even though is CCFL (cold cathode fluorescent tube) backlit).
I'm going to send mine back, but I do have a question. Has anyone got bootcamp running with Vista/XP. I was curious as to whether with a windows based driver the same problem appears? Would be good to know, as if it's a driver issue I won't return my Air. However, I pretty convinced it's a hardware fault - either the coating/alignment of the screen itself - or possibly some kind of interference?
Any people running Vista on their Air?
On a side note the Air rev 2 is the product it should have been originally. It's just a wonderful piece of kit.

It's not a driver issue because it exhibits the same thing when you turn on the computer and the grey boot screen appears.

System Preferences -> Display -> Color
Open the default LCD profile.
Scroll down to number 13 and you should see model number listed there.
So that's two 9C9As with no lines.
OK, someone with lines reply! LOL
Wow, that PowerBook issue really sucked. Took Apple MONTHS to get the issue resolved, and the fix was to ship your PB in for a whole new screen.
I'd guess that if the Air's problem was the same as the hi-rez PB's (horizontal banding), then viewing these two attachments full-screen would make the point clear. They're from the thread you linked to, so all credit goes to the folks who posted them there.
In the pass/fail one, if the FAIL is clear to read, then it's probably the same issue. On the desktopsplitologinscreen one, if it appears that the left side of the screen has a pattern noticeably different from the right, then it's probably the same issue.
Remember that if you click on the attachment in Firefox, it'll open in a new window at a reduced-size. Click on the graphic again to view it at 100%.
My very first Apple purchase was one of those 15" PowerBooks that had the screens with the horizontal banding issue.
Apple finally starting replacing the screens for people that complained, but they never did a general recall or anything. It took a few months of people on the forums here and elsewhere sending in their PowerBook for repair (and getting them back with a new screen that had the same issues) before Apple finally got it nailed out.
If this is a physical screen issue, I really hope that Apple addresses is more promptly and publicly. The only communication on that issue was owners posting in the thread linked to earlier.
