Viewers sitting 5 feet from the screen could read 10-point type, and the projector did a good job of displaying colors accurately, although its reds looked like maroon. The image was significantly brighter at the bottom than the top.

Powered by LEDs, the projector uses only 6 watts of power, about the equivalent of a child's night light. It can run on its 1,050 milli-amp hour battery for 49 minutes between charges, or about 20 minutes shorter than the Pico Projector. Unfortunately, it lacks a battery gauge.

The least expensive of the bunch, the MPro110 comes with a disappointing 90-day warranty; 3M doesn't offer an upgrade to three years of coverage, but Office Depot offers a three-year warranty for an extra $135.

This projector gives an inkling of what's possible when you think small. Business users will love the MPro110's size and weight, but will ultimately be turned off by its image quality and brightness.
