The Adesso Tru-Form 3500 Wireless Ergonomic Keyboard with Trackball is a full-sized keyboard that wirelessly connects up to 30' away from your Windows system. Featuring an integrated trackball, this keyboard delivers full mouse cursor control as well as scrolling capabilities, while maximizing your desk space. The keys sport membrane switches, offering a quiet and smooth typing experience. To help provide a natural typing position, this keyboard features an ergonomic design as well as an integrated palm rest. In addition, multimedia and Windows hotkeys are on board to help you quickly run media and system commands.
The choice between membrane, low-profile, and mechanical switches determines typing feel and noise. Consider ergonomics and layout sizes (full-size vs tenkeyless) based on desk space and numpad reliance. Available from $89.
Keyboards are passive peripherals with almost zero cost of ownership. Wireless models may require occasional battery replacements, but energy costs are negligible.
