Whilst I really enjoy my Black Macbook and really like Mac OS X, I've had quite a few bad ones and thought I'd document it here to share with you guys. 1st Black Macbook (Core Duo): Physical condition was perfect, screen was perfect, no mooing. There was CPU whine but I figure this is normal. Problems: Keyboard had malfunctioning keys (replaced) Screen developed a Buzz (Replaced with 2nd Macbook) 2nd Black Macbook (Core 2 Duo): Physical Condition: Perfect Problems: Screen had a smudge (inside of the LCD) on the top right hand corner, about 2-5mm across (Replaced with 3rd Macbook) 3rd Black Macbook (Core 2 Duo): Problems: Hinge "popped" everytime I opened it and top case had scratches on the corners. (Replaced with 4th Macbook) 4th Black Macbook (Core 2 Duo): Problem: Dead pixel after 2 days. Red is stuck on. So while I really like the Macbooks, I'm really disappointed that I have yet to receive a perfect one. I've decided I'll keep this last one with the pixel since it seems small, I don't have the time anymore to go exchange my laptop and Yorkdale has made it clear that they're not willing to exchange my laptops anymore and will only repair it.
