One of the unsung technological heroes of 2012 was the S Pen, the stylus that accompanied the Galaxy Note handsets and allowed users greater productivity and more features. With the increase in screen size, there have been rumors that the Galaxy S IV will come with its own version of the S Pen and will have some of the same functionality of the tablet/smartphone hybrid. And seeing as how improved the S Pen experience was with the Galaxy Note II over the original Note, if true, we can't wait to see what Samsung has in store for the Galaxy S IV.
