Thats why I am holding off on a case because of the beefiness of the phone
My original assessment of it being the same thickness as the camera bump on my Droid X is spot on... obviously it tapers down a bit on the edges, but overall thickness is there. Unless you need a belt clip, I would say either no case, or a slim silicone cover. Just my $.02
I won a gift card for Invisible shield at Limitless Droid last month so I ordered the fully body kit for the TB, should be here by the time the phone launches, well it will be here next week, not sure if the phone will be though.
I won't be using the screen part from Invisible shield, I like SGP Steinheil Screen protectors more. Invisible shield will wear like iron and protect the body so no case or just a thin slip pouch style for me.
