Have to agree, my Seidio innocase is still in perfect condition after 2 years of use. I've only dropped my phone once though, but still, 2 years of use and it's coating is still 99% perfect. Don't think I've ever witnessed such an amazingly nice and high quality phone case in my life.
I'd get one for the Bionic, but I think I'm going case-less for the next phone I get. I feel like any drop that would break the the screen, would probably break the case anyways. I want to use the phone as it was designed, without a case. I will be using Seidio's screen protectors though, which are incredible. I'm still using the same screen protector I put on my OG from 2 years ago, zero scratches.
