A vendor in the case realm with prototypes at the show, Seidio. iPhone and iPad case products they currently have are mostly familiar (I have one of the iPad models, which believe we have reviewed). Anyhoo, they whipped out a pretty attractive battery case for iPhone 4 potentially to be called the Convert Plus, with a 3-layer construction. The typical composite materials it seemed, but the battery is 1700mAh, light as a feather, and also removeable....interesting, my dear Watson!
