I really hate to say this but I don't think there's any question that quality control has gone downhill at Apple:
MB (non-unibody): Wrist wrest cracking problems (design issue)
MB (unibody): very easily cracked plastics
MBP (non-unibody): Faulty Nvidia GPU, poorly fitted keyboards, poorly aligned cases, yellow-tint on LED-backlit screens, defective batteries, corrosion on cases.
iPod Nano (3rd Gen): Misaligned screens
iPod Touch (1st Gen): Negative blacks
Mac Pro: Audio issues causing serious performance issues
iMac: uh, this article! Plus cracked displays, flickering screens and the aluminium case scratching optical media.
That's just a sample of course, there's far more examples out there and I really wish Apple would a) get it right far more often than they do at the moment and b) actually acknowledge the problem when it comes up. It's the second one really that annoys me the most, these are really expensive machines and to see Apple claim that there aren't any issues when there's clear evidence to the contrary really isn't good enough.
Yeah...
Apple is slowly but surely turning into disaster...
I had "black screen of death" experience with my late 2007 MBP.
Sure, they fixed it within a week (thanks to German authorised service!) free of charge - but still - it was one of the busiest times in my career so far
and 7 days can mean hell of a lot when you are working on few deadlines...
Only few weeks later - power adaptor gave up...
No replacement there - had to buy brand new one >_<
I remember good old PPC days when things used to "just work"...
