"KDE 4.2 is the second major point release for the KDE 4.x
desktop. Its codename, "The Answer," also telegraphs its goals. It
builds on features first revealed in KDE 4.0 with an improved
Plasma desktop interface and KWin window management.
"The new desktop is a challenger to the GNOME Linux desktop and
could also prove to help the Linux ecosystem in its challenge to
Microsoft Windows, as well.
"But the proof is in the end-users' use. KDE's press release on
the 4.2 launch said "the KDE Community is now confident we have a
compelling offering for the majority of end users."
