prosumer

A person in postindustrial society who combines the economic roles of producer and consumer.

During the First Wave most people consumed what they themselves produced. They were neither producers nor consumers in the usual sense. They were instead what might be called "prosumers."

Targeting serious, enthusiastic consumers, incorporating professional features but often modified for non-professional use.

High-end.

A serious, enthusiastic consumer: not professional (earning money), but of similar interest and skills to a (generally lower-level) professional, or aspiring to that.
