This pen is a digital audio recorder and camera built into a large ballpoint pen. It timestamps every note I take using the special spiral-bound notebook with almost imperceptible dot-matrixed paper.

After I finish taking notes, i click the pen on the part of the image or text and the audio recorder plays back whatever was being recorded at that time.

Now, if they can just come out with a 4' x 8' whiteboard version with multiple colors and a portable Aeron chair with lumbar support, I'd be set!
