So I have a new 2012 MBA 13" coming in the mail after selling my 2011 MBP, been wanting the air for quite a while now. So of course, I need a new case for it. I was debating on getting the Colca Hanakapiai which is the best looking case I've seen so far, but now sure if it's right for my functionality. I am a college student so will be carrying the MBA in my backpack with a few notebooks, so the case should protect it from dents/scratches in my bag. Also, when I'm using my laptop I like to place the case underneath the laptop while using it, but it looks like the Colcasac has a bit of a rough exterior, would it scratch my MBA? Thanks!
