"In a recent feature, Neil McAllister asks whether desktop Linux
is too fragmented to succeed. He comments, "Unlike Windows or Mac
OS X, each of which is the product of a single vendor, Linux comes
in many different distributions that target the desktop, and each
has its own look and feel. Some are based on the Gnome desktop
environment, while others use KDE, and still others let the user
choose between both."
"Again, for people who love choice, that's great. But, how many
people are there really who can tell you the differences between
something as 'obvious' as KDE 4.2x and GNOME 2.26 desktop
interfaces. Perhaps a million in the whole world. That's not many
compared to the hundreds of millions who use Windows on a daily
basis."
