How do they all get around if they don't' have cars to drive?
Public transportation is pretty awesome, when well-implemented. A lot of people in Europe have cars, but a lot of them don't. If trains, streetcars, buses, and such suffice to get you where you need to go, why pay for the upkeep of your own vehicle?

Most of the people asking about Windows 10 in the Pi group I take part in are just interested in running "Windows 10" on a cheap computer, and they generally lose interest when they learn that it doesn't even provide a GUI.
