Black iPad Mini scuffing?

We all know about the issues the black IPhone 5 has had with scuffing. I'm curious if anyone is having the same issues with their iPad Minis.

I have had my iPad mini since launch and have brought it with me everyday to work. I have just thrown it in my bag with my lunch and other things with nothing but a smart cover to protect it. I think i have been 'ruggedly cautious' with it if that makes sense. I have not had a single scratch or scuff on the back or chamfered edge.

Anybody having scuff and scratch problems on their black iPad minis? If not, I wonder why the results of scuffing on the iPad and iPhone are any different. Thoughts?
