This article was written from the prospective of an end customer. From a developer/designer standpoint things get murkier. The further one is removed from the technology, the less relevant it becomes. To a developer, the technology can look like a product. An enabling product, but a product nonetheless, and thus it is highly relevant. Bose uses a proprietary signal processing technology to enable products that meet a set of market requirements and thus the technology and what it enables is relevant to them. Their customers are more concerned with how it sounds, what’s the price, what’s the quality, etc., and not so much with how it is achieved, thus the technology used is much less relevant to them.
