I hate hiding my slim and sleek gadgets in big bulky covers, and while I don't (and probably never will ) own an iPad, the new Ultrathin Keyboard Cover which was announced today by Logitech looks the goods. The cover has an ultrathin alumium screen aligned with iPad's built in frame magnets and makes use of the iPad's instant on/off function.  Logitech claims that the Bluetooth wireless keyboard will give you up to 6 months on a full charge (based on 2 hours usage a day), and the built-in stand can be used for typing duties or watching movies.
