Got to call it what it more or less is. Granted it has much function than styluses have had.
I just ordered an Apple Pencil (mostly for notes) and felt pretty silly spending $65ish for it.
Been trying to think of the benefits gained from getting one and here are some things that I've found / come up with.
1. Less Finger Prints. Should in theory cut down on the gunk getting to the screen.
2. Help to interact with UI better ( kind of sceptical about this one )
3. Drawing
4. Writing
I kind of liked the things Samsung did with their Note ( Haven't really used one since the Note 4 ) styluses in the past with the little button on the stylus to initiate different tasks.
Would be nice if Apple had that but I'd imagine Samsung has that patented or something.
