A large 3.5-inch, built-in touchpad makes vertical scrolling intuitive. And multi-touch navigation makes it easier than ever to point and scroll your way through the web. Setup couldn’t be easier – you simply plug the tiny wireless receiver into a USB port and enjoy. Even the hot keys work right out of the box without software. Whether you’re surfing the web or e-mailing a friend, typing is just plain easy with sleek, low-profile keys that feel good and barely make a sound.
