Logitech Wireless Keyboard K360. Beautifully convenient. Conveniently compact. You'll enjoy more comfort with your laptop or netbook and a layout you're used to-in a space-saving design that's about 20% smaller than our standard keyboards. It's virtually hassle-free with a 3-year battery life (Keyboard battery life calculation based on an estimated two million keystrokes/year in an office environment. User experience may vary) and plug-and-play setup that takes seconds. The things you do most are easier too, thanks to six Internet and media hot keys and 12 programmable F-keys. (Programming keys requires Logitech SetPoint software (Windows), available for download at www.logitech.com/downloads). Logitech Advanced 2.4 GHz wireless connectivity gives you the reliability of a cord with wireless convenience and freedom-all in a tiny Logitech Unifying receiver that's small enough to stay in your laptop and lets you add compatible devices to it.
