If you're interested in seeing how modern tablet functionality can be used to enhance old content you definitely need to check out the Glo Bible iPad app. It's one of those apps that's wonderful to use and it will also inspire your thinking about digital content development and presentation.
I recently had the pleasure of interviewing Nelson Saba, CEO of Immersion Digital, the company behind the Glo Bible. We covered a wide variety of topics including the freemium content model, dealing with development for multiple platforms and the community aspect of content. I've embedded the interview below and encourage you to check it out. Nelson is an extremely bright, insightful leader who's produced a wonderfully rich and engaging iPad app.
