Did I really want to spend $100 for a stupid stylus? No, absolutely not. However, I wanted to be able to do some handwritten notes in OneNote on the iPad Pro. Pros: As many have noted, the lag is negligible (one of my main gripes on the Surface Pro 3) The weight of it is very nice and the writing natural I first thought it was fairly dumb to have to be plugging it into the bottom of my iPad to charge, but it really does charge quickly I am able to write in very fine detail Cons: The battery life is about the same as the iPad itself, which for a stylus, is not very impressive (but this balances out by the speed in which it can charge) It's very expensive The detachable cap is d-u-m-m (dumb). Very easy to lose. I would highly suggest paying the few dollars for the cap tether. It really has no home with the iPad (doesn't have a stylus compartment and/or loop Because of this, I bought the magnetic sleeve which allows it to stick to the edge of the iPad In my opinion, Apple should make multiple tips available. If you are like me, I don't particularly like the feel of writing on glass. I would much rather have a rubber like tip, as opposed to hard plastic, to give just a little more resistance when writing, so that it feels more like pen/pencil on paper. But, I have certainly been able to adjust to the feel of the writing the way it is.
I know my cons list is longer than the pros, but considering the purpose of the pencil, the pros have it by a long-shot. I have really grown to enjoy using the pencil and use it almost daily.
