I don't know. I understand what you are saying, but if there was just one Linux desktop it would almost certainly have to be tailored to the lowest common denominator user and it would end up just being a less polished MacOC version. The fragmentation forces some degree of interoperability which enables more specialized and innovative approaches, like tilling window managers,functional package managers, weird shell languages. In other words, the fragmentation might be an innovation and specialization enabling feature, rather than a bug.
