Mini projectorMeasuring just 4" x 3" and weighing less than a pound, the HP Notebook Projection Companion fits easily into a laptop case and projects an image for up to five feet. Its modest 100-lumen bulb should be used only for small audiences; however, in a pinch, it simply shines. The Projection Companion costs $499.
