I’m not in any hurry to go out and drop $1200 on an iPad Pro, but this comparison to the Wacom Cintiq sure makes it hard to resist:

Latency latency latency. As in all that latency I can visibly see as I wait for my stroke to catch up with my Cintiq pen. Oops! Dragged my pen too far because I couldn’t see where the strike would end up? Guess that’s why I mapped 10 of these buttons to Ctrl+Z. This is the game changer with the Apple Pencil, barely any latency so you actually feel like the pencil is leaving ink and can see the outcome of your drawing as its happening.
