I would definitly use an interactive whiteboard in the classroom. It provides the need for visual learners but is much more attention-getting than a simple blackboard or overhead projector. What I really liked was the ability for the students to actually help in the creation process. You teach a concept, then have students create an activity using IWB.
I think the IWB keeps the students more engaged in the learning process, just as the internet does compared to library research. I would have loved to have this technology available to me in school. The possibilities for the use of IWB are near endless and I cant imagine it being boring to students when they would have an active part in their learning. I also think this would be fun for students who may not otherwise have access to computer at home.
