The Work Big IN15 represents the new school of thought for portable projection, maintain outstanding performance while enabling easy transportation. It's not just about compact size any more, but about how well a projector is engineered to pack away and be ready to present at a moment's notice. The IN15 is less than half the total size (in area) than the average meeting room projector and packs equal power. Also the IN15 is about the same thickness as the latest "thin-and-light" laptop computers, which means the IN15 takes up the same space in your briefcase as a few file folders.
