Livescribe’s Pulse Pen records everything that you write and hear.  Never miss a thing again.  Its one of the coolest productivity items I’ve seen in a long time.  I’m not the only one because the Pulse pen was best in show at MacWorld(yes works with Mac), superior rating at PC world, and great reviews from magazines such as Popular Mechanics, and Popular Science.  The Pulse pen is computer in a pen.  It has crystal clear microphone recording, and an infrared camera on the pen that can actually know what your writing and play it back to you.  The Livescribe desktop allows you to transfer notes and recordings, share notes and recordings, and even search for notes done in your own handwriting.  This thing is awesome, you have to see the Pulse Pen from Livescribe.
