This is totally a gadget just for the sake of being a gadget. Which is, indeed, a very good reason. I got fed up with my Britney keychains (left below) constantly breaking (out of the four I’ve had, the three are damaged beyond repair and the fourth is starting to fall apart), so with this electronic solution (right below), I no longer have to fear that. Plus I can carry several pictures now.
Time person of the year 2006, Nobel Peace Prize winner 2012.
