A device you worry about marring with your fingernail isn't one you needle countless times a day with the plastic tip of a digital pen.

And yet, a stylus is the Galaxy Fold's perfect accessory. Everything you'd do on a Note you'd also want to do on the Fold, from navigating around and annotating items, to drawing or writing on the larger surface. Samsung already has this technology down pat, and extending the S Pen to the Fold could help Samsung further differentiate itself from other brands and win more Note fans.
