While on the ModernApps2013 Road Trip stop in Raleigh-Durham, Carl and Richard talk to Aaron Bockover about his experiences building multi-device, cloud centric applications - aka, modern apps. Aaron talks about being part of the rdio team, a music streaming app available for variety of platforms that allows you to move your music stream from device-to-device, controlling one device with another. Working with multiple devices is a hallmark of modern apps, and Aaron digs into what looks easy on the outside, but is deadly hard on the inside.
