Kensington has demoed its upcoming Bluetooth Keyboard Case for the Apple iPad. The keyboard is built into the case, much like the Senna Bluetooth Keyboard case, which effectively turns the iPad into a touch screen netbook. Short cuts to iPad functions such as the homescreen button and media playback functions are included on the keyboard. To power the keyboard, the case integrates a built-in lithium-ion battery that is claimed to last up to three months on a single charge.
