Seido Active Case
I just wanted to post my opinion on the Seido Active Case for the thunderbolt in case anyone was considering it. It's great, I love it. It slides in and out of the pocket a lot better than a rubber/silicone type case yet isn't hard plastic. It protects well. I actually dropped my phone on a hard tile floor here at school and it bounced and twirled and the case and my phone turn out undamaged.
Two negatives, it's not slick hard plastic, but it does take a slightly firmer grip to hang onto it. And if you change your battery a lot, this case may not be for you. It's not hard to take the case off, but it's not near as quick as a silicone case.
Hopefully that helps people in their decisions.
