I don’t like the feeling of the cable dragging on the desk. Or the cable snagging on the monitor stand, or anything else on the desk.
I also prefer the aesthetics of a wireless mouse. One less cable to manage. The charge cable is tucked away and only comes out every week or so to charge overnight.
Yeah, my keyboard has a cable but my keyboard doesn’t move, and it’s a pretty sexy (and heavy) cable so it’s different than a mouse cable.
As for latency, from what I understand in many cases a wireless mouse can have less latency than some wired mice. So that’s nice too.
I guess the main downside is weight but that has never bothered me. That said, I’m not a competitive fps player, but even so some wireless mice are quite light.

Great review of several high end mice, wired and wireless. He found no correlation between wires and latency. Ultimately, he concludes that the most important properties of the mouse are weight and feel.
