One of the reasons I want Library features on external storage is for security purposes. When my eDGe had its library issue it wasn't deleting sensitive files from the Library folder. If they were on an SD Card it wouldn't have been an issue. If I want my wife to use the eDGe or loan it to a friend it would be nice to throw in your own SD Card and keep everything unique to each user. I would think schools might like this as well. I know the iPad has an issue with this. It doesn't support multiple users with unique settings.
