I think Uber's value comes from the fact that they will eventually expand beyond taxi service. They could leverage their network of UberX drivers to disrupt courier and delivery services. Imagine being able to order food from a grocery or restaurant web site that is tied into Uber's system. Uber would alert a nearby driver to stop and pick up your food and deliver it to your house. They could even smartly aggregate the driving, picking up something for you at one restaurant and picking up something from another nearby restaurant for your neighbor.
