Windows Phone has a high net promoter index ie people who own one are very likely to recommend them to others.
The people most often subject to these recommendations are of course our families, which often means that more than one person in a family will own a Windows Phone handset.
In my family it is me and my wife, with my iPhone 5s-totting daughter remaining unconvinced.
This allows better internal tech support, and the use of Windows Phone specific features like Rooms.
