Logitech has now released in Singapore the Wireless Touch Keyboard K400, a new peripheral which enables users to control their PC or laptop-connected TV from a 'safe' distance - up to 33 feet (10 meters).
Logitech's keyboard has a compact design, low-profile keys, a built-in 3.5-inch touchpad backed by two buttons (to eliminate the need for a mouse), and it makes use of the Unifying receiver (which can connect to five more devices, beside the K400).
The Wireless Touch Keyboard K400 has a declared battery life of up to one year and comes with a recommended price tag of S$59 (~ 48 USD).
