My 15" aluminium G4 Powerbook that I bought one year ago, when they were announced, has four "white spots" on the screen. This issue is just now recognized 'officially' by Apple, as this link shows: http://www.apple.com/support/powerbook/displayprogram/ This is good news for me and others on the List who may have this problem - because it means we do not need to fight or argue the case, it is an admitted issue. regards, Trevor
