When it comes to device protection, there's a very large niche that wants to keep things simple. Protection without bulk is really a necessity for so many, otherwise they'd rather just keep their phone naked. Enter the Ultra Thin Air case from Spigen ($19.99), one of the most minimal cases you can get for the N4.
Straight out of the package one thing is clear: this is a no-frills case. And in this case (hahaha, get it?), that's not a bad thing. It gives a very minimal amount of protection, and looks great doing it. My review sample is a matte black little badass – it would make Batman proud.
