BCW published a review on the 3M MPro150 Pocket Projector

3M's MPro15 is a cool piece of gadgetry which any tech-savvy business professional will love. It's no bargain, but it is an easy way tomanage your common business files. And because it's cordless, there's no need to pack a separate laptop or projector so you can travel a lot lighter. The downside is that its display size is limited to 50-inches, it's not very bright, and its built-in speakers aren't loud enough to wake those nodding off at the back of the room. Nevertheless, it probably is good enough to let you leave your laptop at home.
