People tend to run to forums if they notice a problem with their laptop. Majority of people haven't had problems with the laptops or it would have blown up big time and Apple would have been forced to perform a recall. Hope you're enjoying your MBPr! I got mine recently and it's a mega laptop.
That's exactly the point that I was trying to deliver before. It is normal that your machine works just fine, nothing special about that. If anyone who has a normal working machine posts a thread about it, it would become chaos here in this forum
