My iPad has a lot more dust on it than I'd like. Since getting an iPhone 6, I rarely go looking for it. So I'm really interested in the latest changes to iBooks that enable rich media on the iPhone. You probably already own at least one MacSparky Field Guide, so rejoice that you can get them on your phone now too. So many of these have continuing value as reference material so it's nice to be able to have full access when I'm stuck waiting for my life to continue.
