Promethean Board vs. Chalk Board

Some people see a battle brewing between new teachers that are using the new and innovative smart boards and promethean boards and older teachers that still want to stick to their old habits of chalk and erasers. As technology is becoming more and more pervasive, should we shift from the old ways that have seemingly worked so well to embrace this new technology, which hasn't definitively been proven to help students learn better. This debate is a poignant one because how can we truly reach students if we are not bringing technology into the classroom, but how can we forget the traditional ways that students were taught.
