really? dang...my macbook is MESSED up. it's been having random shutdowns and the palm rest is turning orange. i was hoping to wait until thanksgiving break to get it repaired since i won't need it for class, but if this flickering gets worse in the next couple weeks i may have to turn it in early cuz i know i won't be able to stand it. the macbook is my first mac, and i happen to be on my third macbook....not too impressed....I just happen to have insanely bad luck, huh?
