Tired of schlepping your TV with you every time you move apartments? Lighten your load with a palm-sized portable projector instead. Connect the 3M Mobile Projector to your smartphone, laptop or tablet and instantly turn wherever you are — living room or boardroom, bedroom or backyard — into a pop-up cinema. We’re talking crisp resolution you can blow up as large as 100 inches. And if you’re travelling stateside soon, check out a similar portable projector from 3M selling for less than half the price. The picture quality isn’t as good, but it does let you stream films directly from sources such as Netflix.
