The average guest test setup of Magic Mirror required the crew to transport a mini-tower computer, tv or monitor, video mixer, video camera, tripod, and cables. This equipment required 3-4 people to transport. By running Magic Mirror on a laptop, the two most cumbersome components of the system could be replaced with a much smaller, lighter device. Such a setup could allow a crew of 1-3 to easily transport the system.
