Logitech Cordless Freedom Optical

I must say that this is by far the best kb and mouse I've worked with. Logitech knew what they were doing when they made this. The ONLY gripe I have is the mouse sometimes isn't as responsive in FPS games, but then I just plug in my old Intellimouse Explorer 3.0 if I'm dissatisfied. Still, I must say it does a damn good job in most games for a cordless mouse.

Anyone else had good experiences with certain KBs and Mice?
