Unfortunately, I kinda expected having SOME problem with it. A few recent Apple purchases and their failures have been:
• Dual 2.0 G5 - known video card issue, replaced
• iMac G5 20" - known video issue, replaced mobo
• black iPod nano - scratched right out of the box (manufacturing issue, and yes they were real, serious scratches right across the scrollwheel!)
We buy tons of iBooks at my office - comparing all the original, 500MHz iBooks to all the newer G4 ones, the newer ones have had all manner of trouble, compared to barely any with the original ones. We've still got the 500MHz one chugging along...
