For those wondering, I took it in and the "genius" said it was within spec. I asked if he could even just replace the one key to see if it would help but he said for this kind of issue, it would take replacing the entire keyboard or something since the key is on a rubber grommet. I was saying that it seems that my 'E' key is slightly off just a hair so that it lets more light through the gap than the others. Again, he said it would take replacing the entire top or something but, as he saw it, it was within spec. I don't doubt it's within spec, just like if someone has one dead pixel -- sure, their rules say one pixel is ok but that's the company line. A customer irritated by one dead pixel would still ideally like that fixed/replaced. So basically, didn't get the service and understanding I was hoping for. I could have escalated the issue but honestly, I went through a hassle with Apple before regarding a different issue and didn't feel like potentially getting into another. Especially when this seems minor in comparison to the last one. I guess I'll just have to live with it. Good luck to others and if it really bothers you that much, escalate it if you can or even visit a different location -- from my experience, it's random but you may get someone more sympathetic to your issue.
