HardwareZone had a first look at an unversal bluetooth keyboard from ThinkOutside:

The keyboard is powered by two "AAA" batteries and is instantly switched on upon full extension of the keyboard. A green flashing LED that's located above the button "T" reflects the power/Bluetooth status of the keyboard. To conserve electrical power, three minutes of idling will instantly put the Stowaway Bluetooth keyboard into a power-off state, while pressing and holding a key combination of Ctrl + Fn (Blue) + Fn (Green) will fire up the keyboard once more.
