Presumably one could playback not only the videos they personally record using the built in camera but also videos that they have loaded into the phone. For travelers that means if you can find something with HDMI-in (television, monitor or projector) you can watch your videos/movies on something a little more accommodating than the 4.3 inch screen. Combo a unit like this with a lightweight projector and I can see a lot of value for those who do business presentations.
