Smartboards and collaboration / communication

Several people mentioned that they got Smartboards or some type of interactive whiteboard in their classroom. These seem to be all the rage right now. I'm interested in how they are used for student collaboration and learning beyond just presenting information or short "quizzes" using some of the notebook features. I've been reading the research on IWB and Marzano's study (Teaching with Interactive Whiteboards, Educational Leadership; Nov2009, Vol. 67 Issue 3, p80-82, 3p) shows they have an impact on student achievement only if learner-response devices are used with them, graphics are used to represent information, or they are used to present information in an unusual context to reinforce learning.

Have you seen them used as tools for collaboration and communication?
