I love having a holster for my phone, but I prefer the Surface Case & Holster combo, simply so I don't have to worry about the constant rubbing on the phone when I take it in and out. I've had phones in the past and you can see it wearing on the phone casing, and to me, I'd rather not. Don't get me wrong, I love the phone naked, but I'd rather find a case that I like, and a holster, and know that the phone will be better protected in the long run. Plus, I know with my Thunderbolt Surface case and holster, the holster would work with pretty much any snap-on cover, not just Seidio's. So I could switch colors whenever I wanted, and still use the holster. Haven't tried that on the Nexus yet, but I would imagine it should work the same.
