This affordable alternative to interactive whiteboards has an ultra-short throw lens making the projector flexible enough to be ceiling-mounted or simply placed on the tabletop (also allowing the budget hit to be spread to benefit multiple classrooms). The vBoard software lets users write, highlight and edit documents or images in real-time and features an integrated micro USB cable for easy charging.
