This long-awaited projector is about the size of a cellphone. Optoma’s Pico Pocket Projector with a video iPod weighs 4.2 ounces and produces a bright, clear, vivid video or still image.

The review is entertaining in parts – Pogue projects the images onto a plane’s ceiling, leaving passengers baffled. More info from the review: the Pico pocket projector runs on batteries and can project images and videos from a variety of sources like iPhone, iPod and DVD players with a 480x320px resolution and a maximum screen size of 65 inches at 8.5 feet. It uses a non-replaceable 10,000 hour LED lamp and a Texas Instruments DLP chip. It has a 90 minute battery life and can be recharged with its own power cord or through USB.

The street cost for the Pico pocket projector is currently $430.

While not as small as the newly-announced MPro110 pocket projector, Mitsubishi is currently selling a small projector that it calls a “pocket projector.”

The Mitsubishi PK20 SVGA DLP PocketProjector measures just 3.82″ x 4.84″ x 1.90″, and features an ultra-wide lens, allowing you to project a 20-inch diagonal screen from just over a foot away.
