I am currently on the fence as to whether to buy a 27" Refurbished iMac from the online applestore. It's the 2011 model with an i5 processor and HD 6970M 1GB. There's a few questions I'd like to ask to steer me in the direction of purchase: 1) How prevalent is the 6970m failure issue? Has anyone had to go through the trouble of an exchange? 2) Do refurbished macs come with brand new magic mice/keyboards? Or are these part of returned stock too? 3) Are refurbished units covered under the usual 14 day return policy? 4) Do scratches on the screen fall under cosmetic damage? I wouldn't want to receive a less than perfect glass panel on my unit. 5) A frivolous one: Do they come with a new mac smell? Or am i just going to breathe in someone else's cooties?
