Navigate your Windows computer at any angle from up to 30 feet away with Adesso's Wireless Mini Trackball Keyboard. Since it has a built-in optical trackball, scroll wheel and left/right buttons, you'll have full cursor control at your fingertips without the need for a mouse -- and that can save quite a bit of valuable space on your desktop. The trackball itself has a resolution of 800 dpi for accurate tracking with minimal hand movement.
Meanwhile, the slim scissor-switch keys are designed to offer a quieter typing experience and faster key response. This slim key design makes the keyboard slimmer and more lightweight, so it's perfect for travel or on-the-go use.
Additionally, Internet and multimedia hot keys allow for quick access to your favorite tasks like email, volume control and launching your web browser. This keyboard is compatible with Windows 7, Vista, XP and 2000 operating systems. To get started, simply plug the wireless receiver into a USB port on your computer.
