Damon Darlin at the NYTimes reviewed the Livescribe 3 SmartPen, which can take notes digitally, the old fashion way, and has audio recording capabilities to boot:
In the Venn diagram showing People Who Prefer to Take Notes on Paper along with the People Who Want to Store Their Notes Digitally, the overlap is People Who Might Buy a Livescribe 3 pen.
Without a doubt, the pen contains some amazing technology. A tiny camera inside the device records the ballpoint pen’s movement across special dotted paper made to be used with the device. Everything you write or draw during a conversation, interview, meeting or lecture on the dotted paper is transmitted to a nearby iPad or iPhone running the free Livescribe app. You can convert the handwritten notes to text and tag sections with keywords.
