I've had my PB since August 2003 and have had zero LCD issues (pixels, brightness, etc)... but I've notices faint white spots toward the top of the screen. I've tried cleaning the screen but they're still there and can only be seen if the screen is viewed at an angle. Are these the faint white spots that were an issue with the early 15" AlBooks? I doubt these are covered under warranty, but am I wrong? Any tips on preventing these from spreading. I'm a student and carry by book with me but try to be mindful of pressure on the cover. Any suggestions?
