Trackball Keyboards and Keypads - Wireless
Great for use in multi-media development or presentations, these wireless trackball keyboards and trackball keypads combine two input devices in one and eliminate cable clutter. PC and Macintosh compatible models. Receivers plug into available USB port.
A brief note on wireless input devices: You should really ask yourself if you need a wireless input device. Naturally for presentations or applications where you are working at a distance from your computer a wireless device is a necessity but for normal desktop use it can be unnecessarily inconvenient. Wireless devices often require a "synchronization" procedure every time the system is powered up or reset and they are less responsive in games or real time applications. They are also more expensive. Unless you know you really need a wireless device we suggest you go with a conventional cabled device.
