It has developed a blotchy white screen-condition.
Apparently the 15" AluBooks have a known (if not popular) defect where certain uneven spots of screen will start to go dramatically lighter than the rest of the screen.
I hadn’t noticed it until I opened up a white document and noticed these splotches.
Fortunately Apple has fessed up to this unfortunate state of affairs and has sent me a box wherewith to ship back.
I must admit, I’m a bit angsty about being PowerBookless for a few days. Heh, maybe this will be the chance to catch up on my reading instead of working to become King Cocoa.
