How to Hand Draw PowerPoint Presentations

I've been exploring what it means to hand draw PowerPoint presentations. I can't quite put my finger on why but it feels like a massive white elephant perhaps. The announcements yesterday from the World Wide Developer Conference from Cupertino with Apple and their announcement of a new augmented virtual reality headset that they're launching. I'm really curious about it but I'm not curious enough to lay down three and a half thousand dollars to buy it out.
