3M MP410 Projector, $599

Why carry a projector that’s bigger than your laptop when this micro model will do? With a 300 lumens bulb, your PowerPoint slides will look bright and clear. The projector measures 4x4-inches and just under 2-inches tall, and weighs about 13 ounces, so it fits nicely in a laptop bag (with your laptop).
