3M's MPro110 never set out to blow minds, just to wow those who thought projectors could never be this small. According to Gadling's hands-on review, it achieved its goal(s). With a brightness of just 7 lumens, the actual image that it produced wasn't exactly stunning, but it was deemed "far from useless." The biggest knock was just how limited it was in terms of real-world usage; unless the room was perfectly dark, it wasn't the most gorgeous thing to look at, which means those midday sales presentations may not fly if there's a window in the room. In the end, the MPro110 was found to be more of a geek's toy than a proper presentation tool, but who says that's a bad thing?
