Just trying to decide if I should dump my battery eating Logitech G7 mouse in favor of the wired G5. I don't mind swapping batteries but my MX700 was much better on batteries. My PC is on the floor and i am not sure if the cord will reach my PC. I was going to get a USB cable extender so that I wouldn't feel "tethered" by the mouse cord but other than not having to worry about swapping batteries...is there a reason to go with a wired mouse?
