It is a whole new product category. About the size of a cell phone weighing just 4.2 ounces. In the centre of the short end of this tiny black box, there’s a very bright light-emitting-diode lamp. Inside, there’s a miniaturised digital-light-processing (DLP) chip, similar to the ones that drive some HDTV sets. Together, they produce an astonishingly bright, clear, vivid video or still image. It can also run on battery power.
