The Importance of Having a Book

I stopped having a print book now officially about six months ago. I do a lot of video work and actually it's much better for me to be able to present all my, all my workers a body of work. So I show everything that I have three iPads now, or iPad pros that I go around. And I bring them all in depending on how many people I'm meeting. What would be ideal is that I would run a presentation on an iPad mini that would then cast out to the iPads.
