I had a chance to play with the iPevo Interactive Whiteboard ($149) system today. Our school uses the Mimio system which costs around $600-$1000 depending on the model and accessories. The iPevo does everything the Mimio does accept it does some things better! The stylus has an extension (bonus) and a button to click that advances my slides. Here is the biggest bonus: It's small, lightweight, and portable. Look at how all the pieces fit into a pencil case. Oh did I forget to mention the price difference?
