Wireless keyboards are the standard for most people. It's not hard to understand why. Wires are annoying, and the keyboard's wire is one of the few (along with the mouse) you can't hide.  Wireless is so popular that it's no longer a premium feature. Most affordable and mid-range keyboards are wireless, but most high-end keyboards are either wired or offer a choice between wired or wireless models.  Reliability is the key reason. Modern wireless connections work very well, but they're not perfect. Enthusiasts buying high-end keyboards expect the keyboard to register every keystroke every time.  Wired keyboards also provide lower latency than wireless connections. Competitive gamers, who see every millisecond of latency as the difference between winning or losing thousands of dollars at a tournament, universally lean towards the near-perfect latency of a wired keyboard.  Wireless keyboards use batteries. Budget models often use AA or AAA batteries, which tend to last for months but can be annoying to replace. Premium wireless keyboards have built-in batteries that can be recharged. This is convenient but will shorten the keyboard's lifespan. The battery will wear out long before the rest of the keyboard.
