When it comes to Interactive Whiteboards, there are two companies battling for first place: Promethean and SmartTech. Both companies have exceptional software and hardware. The main difference between these two companies is how you interact with the board. SmartTech allows you to use your finger like a mouse cursor to interact with the board and software. On the other hand, Promethean requires that you use a stylus. Both work well, and when used appropriately can be a great tools in the classroom.
