For my own use, games. For example, multiple objects moving: The message updating the position of one taking longer than another shouldn't block the other from being handled. Also, an object being moved over time: You only care about the latest position, within reason. There are other models of simulation that aren't as loose (lock step-style for example). Other messages would not be unreliable/unordered. Important state changes, chat messages, etc. I know voice and video applications can cope with lost packets as well. This is in fact what SCTP was built for.
