PADACS (https://www.padacs.com/cart/) has announced the US$69.95 Toccata, an iPad case that sports a built-in Bluetooth keyboard. Charged by an included USB cable, the Lithium battery-powered keyboard runs for as long as 45 hours, according to PADACS founder Raaj Menon.

As well as the iPad, the Bluetooth 2.0 keyboard works with a range of devices including iPhone 4 and iPhone 3GS (with iOS4) and Bluetooth-enabled devices running Mac OS X, Windows or Linux. The keyboard pairs with devices, going into auto-sleep mode after 10 minutes of inactivity and automatically reconnecting when it’s switched on.
