As fate would have it, my returned PowerBook's screen, while relieved of its white spots, has a yellow pixel line spanning from top to bottom on the right-hand side, and another "clear" line spanning from left to right near the top. You heard right, they sent me a broken replacement screen! It's just my luck. This means that I have to go through the entire repair process again: call Apple, complain, wait for the box to get here, send the PowerBook away, wait 7-10 business days to get it back. To summarize, I will be without my PowerBook for the entire break and probably won't have it back before school starts! Fuck!
Now, I understand that this could have happened anywhere along the shipping path, and surely they didn't send it off with the very apparent lines running through the screen, but none of that helps to quiet my anger. Bleh.
