Along side the Xperia Z4 Tablet debut, Sony also announced the BKB50 Bluetooth keyboard. Oddly bundled in some countries with the Xperia Z4 Tablet which also inflates its price, the new Bluetooth keyboard promises to turn the Z4 Tablet into a more robust productivity machine. In essence, with the  Bluetooth keyboard which has a dock styled connection, your Z4 Tablet can look and act like a laptop. Even better, Sony will be bringing some custom shorts and UI functionality so you can get more out of your tablet. Details after the jump.

The Sony BKB50 Bluetooth keyboard has a hinge mechanism which allows the Xperia Z4 Tablet to easily dock. Once connected, the screen can be titled up to 130 degrees that simulates the same functionality you’d get from a laptop. Even better, while docked, the keyboard and tablet can be fully closed in the same way you’d close a laptop once you’re on the go. Once docked, thanks to NFC, the Bluetooth keyboard can easily be paired to the Z4 Tablet. Other features include an integrated touchpad, and dedicated power button to turn the keyboard on/off.

Once connected, a quick application launcher (think Windows Start menu) will give you access to your recent apps, allowing for quicker use of the things you do the most. Sony hasn’t given any more details about the quick application launcher but it does seem like an intriguing feature, especially if you can customize what populates the screen. With an average 2 hour daily use, the 430 mAh battery should last you an entire month before requiring a charge. Sony has yet to announce a price.
