As you may already be aware, we're part of an elite minority who are generally smitten with pocket projectors. Sure, they haven't found their niche of "usefulness" with the wider world, but that doesn't stop them from being cool to us. 3M's just debuted a new one -- the MPro 120 -- a follow-up to the MPro 110. The MPro 120 projects 12 lumens of brightness (with VGA resolution), a 4:3 aspect ratio, and up to 4 hours of battery life. The MPro is currently pre-ordering for a September 10th delivery in the UK, for £260 (about $423). No word on availability in the US, but we are extremely fond of the projector's rather insane ad, which is after the break.
