Echo Smartpen: A hot mic
It happens all the time: You`re taking notes with a pen and notepad, scribbling furiously, when you begin missing important details. If the pen you`re using is an Echo Smartpen, just push a button and the pen records sound digitally.
I find it really usefull, for work or even school, but as we all know, not all people like to be recoder without knowing. Overall great idea!
