Been rocking a CruzerLite Androidified Clone Army case in smoke. I've been using one on my Galaxy Nexus since I got it and figured I'd give this one a go as well. I definitely dig this case; while the 7 was very easy to hold to start with because of its textured back, this case made it even easier. The Andy's on the back are textured giving you that little bit of extra assurance that you're not going to drop your Nexus, not that you should anyways.
If you're looking for a slim TPU case definitely consider one of these.
