Brand new rMBP 15"/2.6/16GB/1TB/750m. The black hinge cover has a bit of give in the center. I first noticed when picking up the laptop from the backside (e.g. opposite the divot in the case where you open the lid). Thumb on the display, hands on the bottom, opposite the divot, and you notice that that cover squeezes a bit. It's as if it sags a little in the center, and when you squeeze it it compresses closer to the top of the display where it should lie. It makes a little noise when you do so. The distance is small for sure, but noticeable. Nothing else about the hinge appears problematic. It's tight (much tighter than my old 2010 MBP), holds in place, etc. I'm guessing this is just about the hinge cover itself. Anyone else seeing this? I'm trying to figure out if it's an anomaly or typical. If typical, then fine. If indicative of a problem, then I'd prefer to send back and get another.
