Just because wireless mice have improved over the years doesn't mean they should be used over wired.
They should be used because they are handy
1. Signal latency, no matter how you cut it's still sending a signal and no matter what that adds latency.
Latency is below the perceivable threshold since the time of MX700
2. Wireless mice are usually heavy in some cases being anywhere between 300g-700g+
Keyboard included, maybe...
The RAT 9 I tested briefly, is one of the heaviest mice ever touched, and I think is around 180g, my M705 is around 105g, the MX revolution, I believe, is around 140g
in some cases they don't have an internal battery and require external regular (D)AA/(T)AAA adding even more weight to the mouse.
My m705 was bought 2.5 year ago, I have still to replace their batteries, at the extreme end the rat 9 last for 12h or so and have two swappable rechargeable batteries.
Really the only disadvantage is the price, but I don't think that in a place where people is used to spend 100$+ for a set of colored keycaps, 20 euro more for a wireless mouse should matter...
