I checked out the ActivBoard for the first time. Promethean has developed accessories and software to complement their interactive whiteboards. They now bundle a data projector and wall-mounted bracket with whiteboard. They also provide a slate input device, which could be very useful for giving students control of the whiteboard during a lesson. The software seems to provide great value as well. For example, they offer geometry software in which a virtual compass and protractor appear on the screen for performing live measurements. This is worth a try for our next whiteboard purchase.
