Livescribe sells pens that record audio as you write notes, and syncs the two together so you can go back and tap on a note or drawing and hear what was being said at the moment you were writing. The company's newest pen is called the Sky. Unlike previous versions of the pen the Sky uploads your data via Wi-Fi rather than a USB connection. The data is currently uploaded into Evernotes. Each pen comes with 12 month subscription to Evenote Premium.
