It takes 20 minutes to charge fully. Technically, you will use the mouse in "wired" mode for 20 minutes every two months. Instead of using it in 20 minutes wired mode and 2 months free of wires, you prefer to go fully wired. That doesn't make sense.

I don't see wires as a problem. Wireless accessories are slightly more convenient when you're moving the computer around, which is why my work laptop has a wired keyboard plugged into the dock and a wireless mouse with the receiver plugged into the laptop directly, but that's not a concern with my desktop so I go wired there.
