I like it for what it can do as a mobile device. A Wacom Intuos tablet and pen have control and nuance that the Apple Pencil doesn't have (yet). I'm ditching the Wacom only because it's inconvenient and ties me to a computer. The iPad Pro and Pencil gives me enough control and a lot more freedom, so the drawbacks are minor and it's a pretty organic experience, too! I have more time to practice my drawing instead of wondering when I can get my to desk at home or work.
