I guess I can talk about this stuff now!
Rio Music Manager is kind of Emplode-Lite (perhaps "Emplode-Consumer-Friendly" is more accurate). It provides a fast and convenient interface for loading content onto the device, and will be of interest to those that dislike the third party applications that we support. This release is just a taste of what's to come.
Note that the S10 and S30S firmware was written in Cambridge. We think it's the best firmware so far on a device of this size, but obviously it doesn't have much in common with the car player. You'll see many more Rio products from the Cambridge guys over the next several months.
