Default [Q] NC creaking and slight hiss when headphones plugged - exchange or no?

Just want to get some opinions on this.

I used my Nook for extensive reading for the first time today (~2-3 hrs) + listening to music w/ headphones and the creaky noises I noticed all along the right side and top were driving me crazy. Pretty loud creaks and occasionally a soft pop. I don't notice it when I use it with CM7 SD because I'm usually holding it landscape. The hissing noise that some people have reported with plugged in headphones, I didn't notice until today because I hadn't used headphones till now. I tried both my bose in-ear plugs and sony over-ear 'phones, and it was pretty apparent even at lower volumes.

Should I try my luck and exchange it for a new one? Or are they all pretty much like this? I would probably not consider it except for the fact that aside from the creaking the right side feels rather springy when you touch it (the left is solid, no noise) (I'm not squeezing, just pressing down slightly on top). Also, if I look in the seam edge I can see a spot where the white light is coming through.

Am I being overly picky? The creaking is really driving me nuts when I'm reading for a while.. Read for 30 sec, turn page, *creak creakity creak*, repeat.


(If I decide to exchange, should I de-register the device before going to Best Buy, or can I do it there?) I never rooted the EMMC so that's not a concern.


*** EDIT: So I bit the bullet and exchanged it at my local Best Buy. The new one has absolutely no creaking at all, and all four sides of the bevel feel solid (no springy feeling). The rep who helped me opened the new one for me so we could see if it had the same issue, and he immediately noticed the difference. I normally don't return things unless something is broken, but I was concerned that the bevel would eventually become unhinged because the creaking and springiness (press down on top, it would flex and give a mini BOING! feeling into your finger when you let up the pressure) were getting stronger. Screen looks just as stellar as the first, so I'm glad I exchanged it
