Haha, thanks guys.
I am very careful with my Kindle. I treat it with kid gloves, big time. I am very gentle so I don't see why it would crack like that. I wasn't aware of the K2 "hinge" cases when I was reading about the K3 but if they don't have any problems, then I'm sure there are none.
It should get here by the 29th and I already have the Amazon hinge case for it so I will keep it. Thanks guys!
