Anonymous Coward writes "The way John Carroll sees it, Microsoft doesn't get enough credit for all the technology it invents. The company's understanding of the marketplace, argues Carroll, has proved fertile ground for many of the inventions, however incremental, that Microsoft produces on a regular basis. That awareness is that all software markets, however "unrelated" they may seem, have linkages to each other. And it's an awareness that open source will have a hard time matching. Another reason many fail to appreciate Microsoft inventiveness, continues Carroll, is because most inventions are pieces of larger puzzles."
