From a developer's point of view, it is considerably cheaper to bring the HV mains in to a transformer on a street corner and then run one phase in each direction. Putting a transformer at the end of the street andd then running three phases up the street tying each phase into every third house (the way the Govt power co used to do it) is much more expensive, but it does give the home owner the option of having 3-phase. As your user destinations are closer together and therefore closer to the transformer you also get less line losses. Happy now? Theo

From a user point of view, 3 phase gets you a smaller motor, using less amps (but the same amount of power) for better, smoother power delivery. eg, I run a 1hp 3-phase motor on my wood lathe because 1) you can feel the difference in motor pulses in the chisel, and 2) a wood lathe requires frequent starting and stopping and single phase motors get overheated when you do that, as well as 3) the motor would be twice the physical size in single phase.
