I sold my white macbook to my sister and I ordered a 2011 ultimate 13" Air from MacMall. It arrived yesterday (along with my wife's 13" MBP) and I am over the moon. I am so worried about it getting scratched up. Has anyone used the Powersupport Air Jacket? Do you like it? I think it would be great protection when used with a bookbook from 12south. Any ideas?
