The Periscope focused on the drawing but I think what sets the iPad Pro apart is that its not just a drawing tablet, with stylus support rivalling dedicated graphics hardware. The beauty of iPad Pro is that it can still do everything else an iPad can do — it’s a computer. I think the iPad Pro would be a pretty good product (cue the it’s just a big iPad jokes) even if it didn’t have any of the drawing or stylus features. For companies like Disney, they can justify buying them solely as creative tools. For others, it’s a multipurpose marvel.
The lack of a holster or magnetic attachment for the Pencil is an annoying omission, though. The new Microsoft Surface got this bit right: the pen snaps onto the side of the tablet. Apple has left a gaping hole in the accessories market for an iPad Pro case with integrated stylus holder.
