In London at least, Uber is cheaper than using normal taxis, and the process of using an app for ordering and payment is much easier than calling or finding a taxi, and you don't have to worry about having enough cash on you to cover the ride. There are questions of legality here and in other cities (they kind of use a loophole to get around licensing requirements), but at the moment they just provide a better service than any alternatives.
