I found myself wondering how the iPad might work as a Digital Whiteboard, to project, as well as to use collaboratively. I also wondered if there might be some free apps that provide this kind of functionality (there are so many decent free apps for the iPad).
First step, hit the App Store and search for “whiteboard”. I narrowed the search down by selecting Price = “Free” and Customer Rating = “4+ Stars” and found 8 apps. I downloaded each one and spent a little time with them. Four of these apps were pretty cool and definitely worth sharing. The others had drawbacks that led me to eliminate them from further consideration.

This TechSmith app was rated (an average of) 4.5 by hundreds of users. ScreenChomp provides 9 colors but just one pen size. You can import pictures to use as your background. Mostly importantly, you can record your whiteboard session for play back, and the recording will include audio. Recordings can be saved to the ScreenChomps app, and can be shared via email, Facebook, Twitter, and accessed through a URL.
