I can't see any advantage to 120V mains, just disadvantages.
Current consumption would double meaning much beefier cabling - and copper isn't cheap! A 3kW 120V heater, for example, needs a 25A supply.
In the US they also have 240V supplies for the power hungry devices such as washing machines, cookers, driers and so on but I don't think they dual wire the whole house, so any portable devices would have to be 110V.
I think I'll stick with 240V, thank you very much!
