I was sitting with my new macbook pro on my lap. I sometimes sit with my legs crossed (man style) and I put my foot up, and the rubber part of my shoe just ever so slightly rubs my MBP lid and now it has a mark across it. Needless to say I ordered a Zagg full body guard. Just putting it out there, MBP is EASLY scuffed with rubber. No the mark wont come out.
