I think the website OSnews is fishing for comments or missed the mark completely on this article. The article makes a point that a 2003 post which states if Linux is to dominate the world of computers Linux needs to have one and only one desktop.
While the thought has some merit, it has too many fallacies to be treated as anything but noise. Anyone care to drive one specific model of car, sleep in the same brand name bed, eat the same meals as the rest of the world? I think not.
We live in a world filled with choices. Linux is one of the best OS choices for many. Some Linux users obviously feel it is important that Linux as an Operating System rule the world, and dominate Microsoft and Apple. For myself, I need to use all three Operating Systems, and as far as I can see into the future, no single OS has an edge on the other.
I would think we (as in the whole world) have had enough of world domination attempts to know they do not work, and why they are not good for all people. Linux, Microsoft, and Apple are no exception to this idea of domination.. If Linux were to become the worlds OS of choice, Linux would be seen as another Microsoft or Apple, only worse, and a new OS would rise from the trenches and become the favorite of those who are able to make their own choices.
As for OSnews, I hope they achieved their objective, whatever it is.
