Beats the alternatives. Worlds better than any experience I've ever had with a taxi (and more importantly with trying to obtain one).

Android isn't perfect (case in point: it should support saying "yes I want to install the app, no it can't have the permissions it asked for"), but at least it isn't iOS; I'm not going to stick with a feature phone until someone comes up with the perfect smartphone OS. If someone comes up with a service better than Uber, I'll switch. (For instance, I do plan to try Lyft next time I'm in a city it supports, to see if the experience is better.)

Convenience? Price? Lack of competitors (other than Lyft)?
