I received my new retina macbook pro on thursday, this is my first mac I've ever owned and it is the 15 inch 2.3ghz model. What I am noticing is a pretty inconsistent issue, the first being where my palms rest when the machine i believe has warmed a bit the case starts making creaking noises when pressure is applied , the second being the letter 'h' on my keyboard sometimes randomly squeaks along with a few others i belive which i can't pin point since it is so random. I scheduled a genius appointment on wednesday but am worried since those are both inconsistent issues what they will say, i recorded a video on my phone when the creaking was bad that i will show if it comes down to it , i just don't feel good about accepting these issues after how much money i just spent on this notebook, I would love a replacement because i don't really want my 5 day old computer being ripped apart already. Any recommendations for when I go to the genius bar ? Im really hoping the person I deal with is understanding which I think they should be if I'm 5 days in on this computer. Thanks guys
