After reading speekez's thread about the scuff marks on his MBA 11" I decided to check my 13-inch MBA for the same thing. Titled at an angle my MBA has similar sort of scuff marks. Attached image shows the scuff marks. Anyways, I decided to call Apple to see what they could do for me. After being tossed around on the phone for 1.5 hours they finally put a replacement order through. Through the process I was given lots of misinformation. Because of all this misinformation and my time wasted one the lady said she was going to send me a free Speck hard shell case for the 13-inch MBA. Fine, didn't know these hadn't come out yet when I was on the phone, so I didn't say anything about it. She sent me the Speck hard shell case for the previous MBA. After this I was transferred to another person, yet again, and this guy processed the return on the MBA. Finally realized that I was going to be without a computer, for essentially, at least another 1.5 weeks. I was not happy about this, so the guy said he would refund my credit card in the amount of $50. After getting off the phone I realized there were no Speck hard shell cases for the new MBA's. I talked to someone and he went through all of the other cases and bags for the 13-inch MBA. He started talking about messenger bags, but all of the one's on the Apple site did not appeal to me. I told him they should get Timbuk2 messenger bags. He told me that he had never heard of those and he asked me how much one of those bags were. I told him $100. He said ok, let me refund your credit card in the amount of $100, so you can go buy the Timbuk2 bag. I was really surprised and was not expecting this. Basically I get $150 back on my credit card and a brand new MBA. Anyways, that's my story for the day.
