"KDE 4.0 was too radical a change, too lacking in features or
stability, too much a triumph of developer's interests over user's
-- the accusations seemed endless, and only began to quiet six
months later when KDE 4.1 began addressing the shortcomings.
Partly, the hostility continues to this day, although for many the
KDE 4 series has long ago proved itself.
"This April, GNOME 3.0 is scheduled for release. Just as KDE 4.0
was a radical departure from KDE 3.5, so GNOME 3.0 is a radical
departure from GNOME 2.32. But will its release trigger another
user revolt? Or has the GNOME project -- perhaps learning from
KDE's experience -- managed expectations well enough to prevent
history from repeating itself?"
