Do they have any serious scratches or anything on them? I am about to buy one, but I am kind of wondering what it comes with. I am assuming it comes with everything + 1 year warranty. But, it doesn't come with the original box? No one has unboxing video or picture of late 2010 MBA, so I dunno... I would appreciate it if anyone can tell me about those 11.6 refurbished MBA before I pull my trigger.
