I understand there is another thread about the creaking when typing with the rMBP on your lap, but I wanted to know how prevalent creaking is in general. I've used my brother's late 2011 13" MBP that had absolutely no creaking, whereas this new rMBP creaks in certain places. Specifically, if I apply moderate pressure to the right palm rest area next to the touchpad I can always reproduce the creaking sound. Under normal usage, I hardly apply any force on the right palm rest area and there is almost no creaking -- except occasionally. After opening up the bottom plate, I found out that one of the battery assembly underneath the palm rest area creaks when pressed. So the tightness of the bottom plate wasn't the issue, but rather one of those battery "piece." But also, if I press on the bottom case plate near the two palm rest area, I can get it to creak so there is a bit of an issue with the backplate as well. So my question is, is this pretty normal and would you consider exchanging your rMBP for just this issue? I still have 4 days until the end of the exchange period and I also have a written note from a genius for an exchange approval should I want one. If most deem this a minor issue, I don't want to risk getting another rMBP that has other issues.
