Silly question... Returned my rMBP tonight because I wanted the 16G of ram upgrade... While at the store, another customer informed me that when they do custom builds Apple uses previously returned rMBP's. Your chance of getting a bad screen is much higher with custom builds vs the standard configurations right out of the box... On the drive home, it actually got me thinking... Is this accurate? I don't see refurbs available yet, and just from Macrumors customers there must be 100's of them with LG Screens that have been returned... Opinions?
