Having a computer in your pocket that's connected to a world wide web of other devices wasn't viable until the technology too support it was there. If it cost the same as a family vacation to another continent, I'm sure there's no shortage of people that want to experience the weightlessness of space. Think of having drinks (alcohol or not) in space. A simple thing as that would be such an experience. It wouldn't be for everybody, just like cruise ships aren't for everybody, yet that industry manages to stay afloat.
