[I disagree with the case comment, but that's because I find cases annoying and my wife's didn't protect her Nexus 4 worth a darn.]

> The thing slides off of pretty much anything

This is incredibly true. An anecdote: I was sitting in the waiting room at my dentist's office; I knew I'd have a wait, so I turned on the access point so that I could do some work and set the phone on the seat next to me. 15 seconds later, it dropped to the carpet. WTF, so I picked it back up and put it on the center of the chair seat. It fell off 2 minutes later. WTF^2, so I picked it back up and, intentionally and very carefully, put it back on the chair seat. It didn't fall off, but it took me 3 tries to get the phone to sit on a cloth chair seat without falling off. And I'm sure it would have fallen off given more time.
