LiveScribe's Pulse Smart Pen.
I journal in the traditional pen and paper sense, but often I would like to safeguard those writings, and the most sensible way would be on a computer or online.
Well what do you know? They make a pen that will record lectures as you write and then convert your written notes into a pdf file. Pretty awesome huh? The only thing I worry about is the pen itself. I am extremely picky about my pens. I like them very fine. My favorite pen is Office Depot's Foray brand ballpoint click pen with a 0.7 mm point in black or blue. I know, ridiculous me huh? Anyways, check it out =)
