My friend Quentin went to the CES in Las Vegas but encountered so much ridicule for coming back without a cool gadget that he went out and bought a knob! Actually, it’s a “USB Multimedia Controller & Input Device”. If you like jog-shuttle controls, then it’s just the thing. It can be a volume control one minute, and a scrolling controller the next. And it glows in the dark with an eerie blue light. All he needs now is a new PowerBook to go with it.
