It was bought a week ago, and they're made with, what, millions of hours?
I just say so, as speculation, based on my issues with an Apple product within my two week period. I experienced debris behind the screen of the MacBook, which you could clearly see when the screen was on/off. It was only because I moaned about getting a refund and their quality control, all while noting my $21,000 lawsuit with Dell, that they gave me a replacement. That said, these debris are far more concrete evidence of a defective product versus something the OP perceives over the course of a week; the genius has never seen the MacBook before.
Purposely ignoring issues plaguing an entire computer model line and using deceitful marketing ploys to scam me out of $955.83. Phone support totaled over 40+ hours and online connections with them for some 4 hours, all documented. I was sent three replacement computers and enough parts for two extra computers. I was lied to, cheated out of, and scammed of my time and money. But the lawsuit will never see light, as Dell would be stupid not to refund me the $1,000 I paid for the system rather than risk a day in court. The only reasons it's over $1,000 is for legal fees, should I go to court.
I've been promised a full refund by high levels of authority at Dell twice before the lawsuit; this is just to boost it along and to make sure they deliver what they said they will deliver. The defect it actually noted in the BIOS delivered with the system based on the fan they deliver which essentially causes it to overclock to speeds it isn't usually capable of doing. And the marketing thing is debatable, but I submitted to the same attorney that took on Dell's case about the fraud.[1]
