bought a new unibody today. I was sweating like a pig the whole way home hoping that I wouldnt get a dead or stuck pixel. Im always so scared that it will end up having a stuck green pixel or stuck red pixel right smack in the middle of the screen. just enough to aggravate the living crap out of you every time you turn it on. plus i was reading all kinds of horror stories of people having to bring their macbook back 2 sometimes 3 times just to get a good screen. anyone have to swap out their macbook because of a pixel issue. how bad was it. color location?
