LiveScribe and SmartPen look like great tools for researching stories and conducting interviews. The SmartPen also records audio. You can touch any place in handwritten notes to play back the associated recording. The main drawback I see is it wouldn't help with phone interviews (so maybe I need to start using Skype). Any advice for the techno-challenged? Has anyone else experienced using this product? Comparisons with iPad? Other digital pens?
