I just got so fed up with the mouse that I have right now (wired optical mouse from Microsoft) that I threw it and it broke. The right button wouldn't click anymore and the pointer wouldn't move straight according to how I moved the mouse, so I'm stuck using the laptop touchpad for now. I'm going to have to go get a new mouse tomorrow before the NFL games start. Anyone have a wireless mouse or have used one? Are these worth it? Should I get one of those or would I be better off staying with a regular wired one? Are batteries usually good? Input appreciated!
