I'm going to head over to Best Buy tomorrow and pick up a new keyboard and mouse. My old ones are both PS2. I've never owned a USB component before, so I was wondering if I should stick with PS2, or make use of the USB ports? I don't really have any reason for or against it, I guess I could go by price, but I bet even that is similar. Any suggestions? I'm looking into an optical Logitech mouse.
