I was bumbed out when the "white spots" started to appear on my screen (G4 15") bought last year. I called apple care and was told "Up to 6 dead pixels are to be accepted and warranty would not cover it ". I had 3. Turns out they were not dead pixels but "white spots" Looked it up at Apples site and found recall on given S/Ns. Sure enough I had a different number but took my lap in anyway. Tech saw it and honored it with 2 days left on my warranty !
