I just received my refurbished Macbook Pro 17" from Apple on Friday. Today, I can see a round discoloration on the right side of my palm rest. I've seen some references to this on Apple's web support site, but no resolution is posted anymore and the discussions are locked. Are they sweeping this under the rug or is there a known issue that I can call Apple for? Honestly, either way I am calling Apple tomorrow. Please let me know what the latest info is on this.... Please... Thanks!
