Aura HD Improving Grip [sandpaper anyone?]

Aura HD has a nice back design, but let's be realistic, the texture is very slippery and it reflects fingerprints which looks very ugly.
It could feel (and look!) better if it was knurled like the back of most Samsung phones.

I'm thinking about sandpapering the back of Aura HD, but I'm almost certain it will look ugly, but the grip will be awesome!

Anyone have any better idea?
