Logitech has a couple of new gaming mice that are getting great feedback. The G5 looks really nice and since I am back playing mostly FPS it is time to hangup the cordless mouse. I was using a MX1000 which was not very suited for a FPS. Too heavy and noticeable lag. I am using my old intellimouse until I pickup a G5. The only thing I don't understand is why they only have one side button. The MX1000 had a bunch of extra buttons which was very nice and the one thing I will miss.
