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 $29.99.
Keyboards are passive peripherals with almost zero cost of ownership. Wireless models may require occasional battery replacements, but energy costs are negligible.
Common Failure Modes
Liquid spills and physical debris are the primary killers of keyboards. Mechanical switches can develop 'chatter' (registering double keystrokes), while membrane domes lose elasticity.
