I just bought a new Powerbook 15" (love it) and although the keyboard and touchpad work, I'd like to get an external keyboard and mouse for my dorm room, preferably wireless as I only have two usb ports and don't feel like spending money on a hub. I've been looking into the logitech wireless navigator duo and have been getting mixed reviews. Does anybody have a logitech keyboard/mouse or any other external one that they've had a good experience with?
