Pint-Size Digital Projectors are in the works. These devices, when plugged into cell phones and portable media players, will let consumers beam video content from their hand-held devices to the closest smooth surface. The micro-projectors, still in prototype, use light-emitting diodes and lasers to cast a display 60 inches or more in darkened spaces and 7 to 20 inches when there is ambient light. Eventually projectors will be embedded in cell phones, just like cameras.
