While we live in a world where people use their thumbs to type on touchscreens, the pen remains one of the most used tools in human history to date. As we gear up for the imminent arrival of the Samsung Galaxy Note 5 in the next few days, Samsung have come out with an article describing the role of various pens in human history with perhaps the inclusion of Samsung's own S Pen stylus. Currently available on Samsung devices like the Samsung Galaxy Note 4 and other Galaxy Note devices, the S Pen can be used to replace your mouse and keyboard while giving your thumbs a rest as well. Check out Samsung's take on the role of pens (and the S Pen) in this article or see our review of the Samsung Galaxy Note 4 as well.
