I received my matte graphite and just installed it. (Sorry, no pics right now as I'm exhausted).
I like the look and feel of the material. I'm a little disappointed in just how "matte" it is. I was hoping it would have a little more sheen or sparkle.
The cutouts all seem to be on target and you definitely get the feeling that the case is well made. I had no problems installing it.
I think it will provide pretty great protection, however I'm a little uncomfortable with the sharpness of the edges. It feels very....edgy. Lol. I know that doesn't make sense, but it is a pretty sharp angle and I think a slightly more rounded edge would be more comfortable.
Wifi is great, with no signal loss (crossing fingers). However, I have noticed a 1-2 bar drop on AT&T coverage here at home. Hopefully it's a fluke...
