I picked up a used Air on CL yesterday. The guy had barely used it for a day, the adapter and cable were still wrapped and it was basically tried out, he decided he didn't like it and got rid of it. I noticed there's already a decently-deep scratch in the screen (I didn't notice at the time). That seems odd to me given I've had my Mini since launch day and, while I have a SmartCover, I'm not overly protective of it and have been known to lay it face down without the cover on, and my screen is flawless. Is the Air screen that much thinner/softer that its' going to be more prone to scratches? This is not scratchgate/fear-mongering/OMGiPADAIRISTHESUCK, it's just a question. I really don't care one way or another, just asking.
