Move over pens, it's time to make room for a pocket projector. Yes, projector, not protector. The 3M Pocket Projector is a dinky $359 projector that takes the place of hyper-expensive LCD projectors that can run in the thousands. Plug the projector into your laptop to access DVDs, presentations and photos, and project them onto your desk or wall or another blank white space. It's definitely limited to a smaller room application in bright light - it displays around a foot across - but in a dark room, you can use it to project a much larger image on the wall. Perfect tool for taking on the road for seminars or doing quick displays.
