I'll offer up the following perspective to the conversation with respect to integrating interactive whiteboards into TBL classes:

Before adopting any specific educational technology, I'd recommend you articulate the educational problem/situation you're facing. Ultimately, you want to ensure you're selecting the most appropriate technology to address the situation/performance gap you're facing. There's no point starting with the technology that's looking for a solution.

Based on my experience, interactive whiteboard manufacturers, such as SMART Technologies, have done a good job convincing educational institutions that they need interactive whiteboards in the 'classroom-of-the-future', boards whose design and placement in the classroom tend to align with a presentation-of-information paradigm and favour instructor-board interactivity vs. student-board interactivity.
