I have this case in the grey color. It's a touch smoother than I expected but still makes the phone easier to hold then having no case.
I also ordered the Casemate Barely There case and compared to that one, this Feather is just a bit thicker. However, the Feather case has a lip on the edges that lets you place the phone face down and the screen will not be touching the surface of the table or whatever. It's not listed as a feature. Ironically, the Casemate advertises that it has this lip and the case they sent me does not.
I think in a perfect world, I'd like to get the Casemate Barely There in this grey color. I'm not a big fan of the plain black case on such a pretty grey phone.
