Kubuntu LTS and KDE4

The opinions on LinuxToday you linked to are more than two years old.  Today, it is clear that
SUSE has continued to release new products in the Linux desktop product line (rather than kill
it as one story suggests).  SUSE Linux Enterprise Desktop 10, with KDE and GNOME, seems to be
doing well, based on the news over the last few months about various hardware companies
preloading it.

As for your comment on LT, which you linked to, I would suggest that openSUSE has a top-notch
KDE desktop.  The openSUSE project manager is a KDE hacker:

Lastly, if you follow Ubuntu at all, you know Mark truely runs it.  He was involved with
Debian before and is the SABDFL (Self-Appointed Benevolent Dictator For Life) for Ubuntu.
