improbably-small projectors we've been seeing around for the past year or so are starting to land in force, and 3M's MPro110 is certainly a contender. The little unit shoots a VGA image onto screens as large as 50-inches (though we wouldn't recommend it), with a long lasting LED backlight backing it up. We got an up-close look at the thing last night, and have a few quick notes: the image is about as dim as you'd expect, and looks exponentially better the smaller the area you're trying to project on -- at about 30-inches in a decently lit room the image was insufferably dim, but at around 17 or 18-inches we were getting some pretty good definition brightness. The projector autofocuses plenty fast, which is clutch for a "handheld" projector, but it does get fairly warm despite its LED usage. Overall, we can't fault the projector too much, with a $359 pricetag and a "paperback book" form factor, but the application is certainly limited at the moment, and we're guessing these will be getting a lot better in the future. The MPro110 is now shipping.
