I'm not sure how this happened, but my Al15 developed a fairly prominent scratch on the outside of the screen (about 2 inches long). I guess something must've found its way between the powerbook and the inside of my bag.
I used turtle wax to buff out scratches on my iBook with lots of success... but I'm a little more hesitant to experiment with this computer... has anyone else tried buffing out scratches on their AlBooks? What did you use, and with how much success?
