Adesso Wireless Rf Mini USB Keyboard with Optical Trackball

Adesso's Wireless Mini Keyboard With Optical trackball allows you to work up to 100 feet away from your computer. It connects with the computer by a 2.4GHz rf signal broadcast to a dongle you plug into a USB port. The optical trackball is extremely sensitive, with 800 dpi resolution. The keyboard's light weight and well-thought-out assortment of mouse buttons (for both hands), scroll wheel and hotkeys provide excellent ergonomics. The different hotkeys give quick access to common tasks such as e-mail access, volume control, and launching your web browser. Although the fact is not noted in the packaging or on Addesso's web site, the Wireless Mini Keyboard works perfectly with a Mac (including the hotkeys), although the keyboard layout is geared more toward a Windows PC. It is plug-and-play -- no software installation required.
