The article "Google Chrome OS. Or, how KDE and GNOME managed to shoot each other dead" is intentionally outspoken and controversial. It invites comment and criticism - one can hardly declare two of the best known and most widely used Free Software projects to be "dead" without causing uproar.
A key part of the author's argument is that Google Chrome OS is likely to be both valuable to the public, and also very widely used. I'd like to contest the first part of this assumption.
