The Gadgeteer has reviewed a lot of Booq cases over the years. They make cases and bags for Apple products, so it’s no surprise they’ve introduced the Viper Slider Case for iPad 2. This two-piece case slides over the back of the iPad 2; the bottom half slides off so you can use the iPad 2 in a dock. All ports and controls are open and accessible. The case is made of leatherette-wrapped polycarbonate for protection against knocks, and it’s lined with a soft fabric to prevent scratches. It sells for $39.95, and the estimated ship date is 5/5/2011.
