I have owned a couple other generation of the ipad with that I also bought a few different styluses with the intention of using them to sketch with. I have never really liked the sketching experience, Until Now.
I find the apple pencil to be really responsive, and the palm recognition works really well. I almost prefer using the ipad Pro to the Wacom Cintiq.
Overall Design of the Pencil is pretty nice; it feels good in the hand and has a good weight to it, however there are some flaws. I will start out with the obvious flaws, charging the pencil. The Pencil charges in the bottom of the ipad via Lightning port and every time I plug it in I am either scared the port will snap off and break or I will loose the end cap. I am always extra cautious while charging. Another issue is that I found the pencil to be a bit slippery. Although the Gloss finish looks cool, a slight texture might make it less slippery. Since the Pencil is a perfect cylinder I find that it rolls off my desk or workspace quite often. Adding a minor Flat edge or something to help it from rolling would be helpful for me.
so far i am really enjoying sketching with the ipad, I am excited to see what the future holds
