Using a wireless mouse is a much more pleasant experience than a wired one, which is always giving a little resistance in one direction due to the wire.

As for keyboards, a lot of people move their keyboard. For example, I move mine from my standing desk when standing, to a keyboard tray when sitting, since no one can seem to manufacture a standing desk converter with proper ergonomics when sitting. The keyboard always ends up at desk level, instead of just below. Unfortunately, they don't make a wireless version of my favorite keyboard, and the wire is always getting in the way when converting.
