Another tech trade show, another pico projector from 3M. This time round it's the MPro150, described as the "ultimate personal electronics device for the business professional".

The MPro150 is unveiled with the boast of owning one of the most robust feature sets of any pocket projector currently on the market.

The 5-inch pocket-friendly device includes 1GB internal memory, a microSD card slot and a USB input and supports Microsoft Office applications as well as Adobe PDFs, photos and video.

The small-scale device allows projection up to 50-inches at 15 lumens brightness while other features include an integrated MP3 player, headphone jack and integrated stereo speakers.

Other bits of note are the built-in flip stand, tripod and a variety of input cables, in a bundle due to cost $395 with orders due to begin shipping in early February.
