Enormous feats of shrinkage like that donít come along very often, though. So when they do, you sit up and take notice ó as you will the first time you see the Optoma Pico Projector ($430 list price). Itís a long-awaited, much-rumored projector about the size of a cellphone: 2 by 4.1 by 0.7 inches, weighing 4.2 ounces.
A pocket projector? Are you kidding? This isnít just a new product ó itís a whole new product category.
Youíd have to be a jaded gizmophile indeed not to be impressed the first time you turn on this tiny, shiny black box. In the center of the short end, thereís a very bright light-emitting-diode lamp. Inside, thereís a miniaturized Texas Instruments digital-light-processing (D.L.P.) chip, similar in principle to the ones that drive some full-size HDTV sets. Together, they produce an astonishingly bright, clear, vivid video or still image. Thatís right ó from a projector youíve pulled from your jeans pocket.
