Answer 1

You only know a very small part of the story.   THE ORIGINAL iMAC WAS ONLY JUST OVER A MONTH OLD!  The original Appointment was screwed up by Apple Support(?).  I was told to drop it off in the morning and return for the 3:15PM appointment, which I did only to find there had been no appointment made, but the case number was in the system.  I was told 3-5 days only to be notified by e-mail on the third day the logic board (motherboard) was bad.   Another wait.  A week later it was ready and it ran from about noon until the next day about 11 AM when it had an update that required a restart where is promptly died during the restart.  The Mgr of the Apple Store was gracious and had the computer replaced with a new one rather than trying something else.   Perhaps, you think it is fun to sit in a noisy store for half an hour or more, but I sure don't.  Where is Apple's QC??? China!  
I owned a computer business for 15 years and never once made a customer go through this much trouble.
If my computers made it through a 72 hour burn-in and did not have a problem in the next couple of weeks it never did have a failure.   My 15 year record of building computers had less than a 1% failure rate. 
By the way, for your information if a new logic board is installed (I seemed to see several being done each visit) and the App does not recognize it, just uninstall it and go to the App store and re-install it.
