I have had the original DPT-S1 since 2015. I got it before starting school and have used it for textbooks throughout. Weighs a few pounds less than any textbook, let alone all my textbooks. For this it is amazing. For handwriting... Not so much. Can only write with one hand in one orientation. New split screen mode is pretty tantalizing. I could be persuaded to upgrade if this model has a better stylus situation--I could stop carrying a notebook altogether most days. P.S. To the sony employees out thre: A graphing app would be amazing
