My new Macbook Air has some dark spots / shadows in the lower corners and along the lower side. It is very hard to take a picture, but I found an extreme example (it's far less in my case) that shows the effect: http://www.lavproductions.com/images/macbookpro_screen.jpg It is only noticeable on a white background. Does anyone else with the new Macbook Air see the same kind of spots? Should I be worried/exchange my Macbook Air (1 day old)? I've already been to an Apple Reseller to look at the showmodels, and they show the same defect.
