Folks, I am looking for an electronic writing pad that I can use to deliver lessons with hand written illustrations. I want to make videos so that it feels like a teacher with a marker pen scribbling on a white board while talking. I try with mouse but the writing becomes so edgy and unattractive. Is there an electronic pen with special pad that I can use for this purpose. Preferably the pen/pad combination should have microphone input so that the scribblings are synchronized with the lecture/narration.
