8. Potential problems Some functions of powerpoint may not work, e.g. notes, transitions, automation... Student presentations must be submitted in advance. Conversion from full powerpoint file to cut down file must be done on a computer linked to the device. Bluetooth may present security risks.

9. Potential solutions Removes the need for a laptop making presentations mobile and perhaps faster to set up. Reduces security risks e.g. loss of laptop. Standalone ability: some may project display directly, without the PDA. Most remove the wires, freedom to present and interact with audience. Adds functionality to PDAs and smartphones.
