I just opened up my brand new 13" rMBP that I bought on Saturday. Fired it up and so on and when I hit the enter key, it didn't depress. I tapped it a few more times and depending on where I tapped it, it would or would not go down. Looking closer, I can see in the gap between the key and the aluminum something is there preventing it from going down along the bottom half of the button. This is an expensive machine so I don't want to go prying off keys. Does it look like a loose screw or something? I don't want to start off with a Genius repair...hopefully I can just take it back to Best Buy for an even exchange. Thanks!
