I recently bought a 13" MBA. I'm seeing some backlight unevenness and am wondering if any of you have the same problem. The first image is at 10% brightness. You can see two-thirds to the right a darker area that's around 2" x 2." The second image is at 30% brightness and the third one is at 70%. I have to say it's a non issue at 70% brightness. I'm overall very pleased with the machine. It's slightly annoying when I'm on battery and want to view emails at the lower bottom right of the screen.
