In order to keep the HTC EVO in top-notch condition while in use, most people put it in a silicone skin, snap-on shield, or some kind of hard case, with or without a holster. This protects the phone's back and also covers so much of the hardware that it doesn't really matter whether the bits showing through are black or white.
I keep all of my favorite gadgets in leather pouches because I prefer to use the devices in their natural states. If something is beautiful and thin, I don't want to hide or fatten it up. I've reviewed a couple of leather pouches so far (more are on the way) but am still in search of something that I really like and actually want to use (Vaja and Noreve, where are you?). So I'm still babying my EVO with a microfiber blanket when I take it out of the house.
What are you using with your EVO? Are you happy with your choice or still looking for something better?
