I tried it with an iPad class this week. .pretty cool..

JerryButler: please share your thoughts, experiences, and how you feel it is valuable. Thanks

It seems to offer some value for students to collaborate with each other on say correctly solving a math problem. they share the white board so to speak and can narrate their discussion.. or draw out a diagram.

JerryButler: Do you see any use for this app beyond math? I could see how it might help with Physical Education as well.

Anything that could be drawn or diagrammed out. I wish it had keyboard input. You could scan in a document and mark it up - grammar, parts of sentences?

JerryButler: I sent that and a few other app update request to the Techsmith folks. Keep your fingers crossed
