This cool gadget is a pen and a computer all in one. With this pen, when your writings it also records audio so whenever you go back threw your note is plays the audio at the same time your reading the notes. A really cool idea and is worth getting for people who take a lot of notes like college students or working writing professionals. I guess if the police got used this pen when taking statements it might help fight crime to. A lot of great uses for the Livescribe Smartpen and I am looking forward to getting my hands on at least one of these pens when they hit the market early this year.
