I know, I have to change out my wireless mouse batteries ever 12 months, it's exhausting.
its more than just changing them out... and if you get 12 months use out of batteries, I'm surprised. The wireless mice and keyboards always seem to have issues remaining connected, and it gets worse when the batteries get low. Or the computer starts complaining about low batteries at 20%. If you get 12 months, than thats a couple of months worth of warning.
Not to mention, they simply are NOT as accurate. I can take my wired mouse, move it around to a different monitor, and it stops when I stop it. With their wireless mice, if I go from one monitor to another one quickly, the pointer almost always keeps moving a little bit after I stop it.
If I have to hold down the option key to select another boot volume, or boot into single user mode, half the time it doesn't work with wireless keyboards. I have had almost every single one apple has ever made and some third party ones.
With a wired mouse and keyboard, I never have to worry if the mac is going to "see" the mouse or keyboard. It just works.

I fail to see how wireless mice are any more inaccurate than wired mice's.
they are not less accurate as far as pin pointing a specific location, but they aren't as accurate moving them there.
