OMG this is my exact setup. I bought an iPad Pro a year ago and figured might as well get the fancy pencil with it... it's by far the best tech purchase I've made in a long time. I use this device every day. The Jamboard app especially is great because I can join the same link from a laptop and present my drawing over HDMI.
Jamboard pro tip: if you open the "board switcher" drawer and press the three dots, you can change the background to grid or dot paper. Game changer for sketching diagrams.
Another great app for drawing is Procreate, which gives me layers, and has better drawing tools, like morphing my crooked lines into straight lines and perfect circles. Nice for sketching interfaces.
