Hello all, First post! I have been lurking around the forum for quite some time. I decided to pick up a macbook pro today because I was able to get a pretty good educational discount. I have the 15" MacBook Pro top end with the matte screen. Everything seems perfect right now. However, even when the volume is at 50%, and I play something that has bass in it, the RIGHT palm rest shakes/vibrates a lot, and you can feel it. It is a tad bit annoying. I was wondering if this was normal. Thanks!
