This is why the open source movement is so interesting, we're seeing competition and innovation in Operating Systems like never before. The cost of taking world-class components (like the kernel, filesystems, windowing systems) is so low that it makes sense for people and companies to experiment, as we're seeing now. Chrome OS would be prohibitively expensive to develop if they weren't able to take so much off of the shelf.
