After hearing about the issue with the iPod touch having that negative black effect and all got me noticing that my 2 month old black Macbook has a very similar problem. I don't know if this is normal on Macbooks, but for mine, if the angle of the screen is too far back, you can definitely see a negative black effect. If you angle it perfectly, its much less noticeable. I'd like to know if this is normal on Macbooks and if there's anything I can do about it if it is? Also, the screen that I have has some light leaking on the bottom. I've seen worse on YouTube, but I've always figured that all Macbooks had this problem and they just used bad screens (at least for Macbooks). Thanks.
