One of the nice things with RODCs is the ability to control cached credentials.  You can also pre-populate passwords for specific users, like a branch office user, in case the branch office connection goes down but this can be a security concern if that server gets stolen.  Server 2008 has a nice way of handling this so you can sleep easier.  This last video will cover what to do when the RODC is stolen.
