I have switched to wireless mice. I've bought the cheapest on offer. Two are Logitech and one is branded Microsoft. I just plugged them in and have never downloaded any software. They have been trouble-free. Battery life is so good that I forget the last time I replaced a battery. The Logitechs have a red LED which blinks when the bat is getting low. The latest one claims really long battery life. I usually leave the mouse turned on even when I am not using the computer.
The only time I ran into a problem whas when I was about to give a talk. My wireless mouse drowned out the mouse of the speaker who preceeded me. Simple fix was to turn off my mouse until it was my turn to talk.
