Pen Doubles as Secret Voice Recorder/MP3 Player

This thing is like a journalist's best friend. And here's why: Not only is it a pen, but it is also a voice recorder and MP3 player. Basically you can set it down inconspicuously on a table to record a conversation--the "record" button is the silver knob on the pen cap, so if your handwritten notes aren't keeping up with the dialogue, you can simply turn the thing on and stop writing. The LED light at the base of the USB thing tells you what function's in play, whether it's playing music (green), recording a convo (orange), or playing back a previous recording (yellow).
