How many non-X Linux distributions fit his description? "For use as a desktop PC operating system, all the various “Linux distributions” are basically the same thing: variations of Gnome or KDE sitting atop the ancient X Window System." It seems like Chrome OS will be the only non-X distribution which is a serious option for widespread desktop use. There are non-X distributions, but not desktop non-X distributions. If you want to dispute by adding Xfce or whatnot to Gnome and KDE, go ahead, but I don't think it's relevant to his main point: the mainstream desktop Linux distributions are all pretty much the same experience.
