I used a wireless mouse before. didn't like it cause when the batteries die, there is no warning. You'll be playing a game and there will be a not so noticeable lag. then it will get worse. and worse, until the cursor is jumping around the screen and you think the puter is locking up. I got killed in to many games and went back to good, optical corded mice.
Just my 2 cents.
