It's very well possible my wireless mouse setup has lower latency than most wired setups.
That’s why I said essentially no lag. A good gaming wireless mouse will do better than many wired mice. In those cases it’s better but it’s still not enough difference to matter to anyone.
The advantage of wired is not just aesthetics. This thread started because of any accessory to deal with the wire. I don't need to bother at all with a damn wire in the way.
> This might as be considered a law of physics - electromagnetic energy will always travel faster, more accurately, with less interference, with less required current through a conductive medium than through air.
I mean you might want to go back and read a high school physics textbook - because you’ve got the speed of light exactly backwards.
The reason digital wireless signals may have additional latency has nothing to do with the propagation which is faster in air.
Also I’ve never seen a networking over powerline system that worked better than Wi-Fi. Not all conductive paths are effective for signals.
> Wired is ALWAYS the objectively superior option in all metrics except for superficial & subjective "aesthetics", all else equal.
Which is why professional musicians and broadcasters would never use wireless microphones and pickups. (sarcasm)
