This is a very interesting interview with Kobo CEO Michael Tamblyn. He goes into a lot of detail around ereader use cases, development, integrations, and how Kobo values the consumer's ability to access their books and take them to other devices.
Tamblyn comes on about halfway through the video (the segments are well marked if you hover over the progress bar).
