Thanks to Chantal for this great link: 7 Lessons in Magazine iPad App Design: A Master Class with Creative Director Robert Newman
Some ideas he touches on:
-plan it out on the wall, together
-interactive, but give some breathing room as well
-redesigning features is easy, redesigning departments is hard
-digital design planning influencing print templates (RD used as a sample image)
-dual or single orientation?
-digital covers should match print covers
