Abstract:

Microportable and ultraportable projectors are changing how Corporate America presents information, sells products and trains employees and customers. Small enough to fit in a brief case, light enough to carry from appointment to appointment and easy enough to use without extensive training, these projectors deliver big, brilliant video, graphic and data images that are sure to grab and hold the attention of audiences.
