Crux has recently announced their new iPad 2 case to basically put it on steroids. Crux are the makers of the 360 cases for both the iPad and iPad 2. The new case is called Crux Loaded, and it is just that.
The new case features a Bluetooth keyboard and trackpad as well as an extended battery, which Crux says will give you an additional 7.5 hours of battery life. You can keep the same functionality with the trackpad, using multitouch gestures and scrolling.
The case will become available this fall for $249 on their website.
