After using Addison Lee for the past year, I finally gave Uber a try, and I must say...I absolutely loved it! Uber is a car for hire service and is managed through a smartphone mobile app. You basically just fire up the app, identify your location (using your phone's GPS), specify where you want to go, and then book your driver. It even gives you car options, such as a standard, executive, or luxury car for your journey. The app also provides you with your journey's estimated total fare and when you can expect your pickup.
