I did a talk on Cupboard at the excellent Droidcon UK conference this year. The talk was recorded and published at Skills Matter. The talk outlines some of the history and goals of Cupboard and shows a few examples of using the library from different contexts. You can checkout the video from this link: http://skillsmatter.com/podcast/os-mobile-server/simple-persistence-with-cupboard

I’ve also recently set up a Google+ Community for Cupboard, where we can have a friendly discussion about anything related to Cupboard, like feature requests, issues or general questions. Feel free to join, I’m really curious and exciting to hear how Cupboard is used in the wild!
