Two KDE articles at opposing ends of the spectrum.
This is a nice review of some of the cool plasmoids that are available in KDE 4 and shows that they seem to be taking off in a good way. Always room for more and I am sure as time goes on we will see lots more arriving.
(Also a great way in to KDE coding!)
This is a review of Fedora with KDE. The chap that writes the review raises some interesting points. I would be keen to find out if the issues are KDE related or Fedora related. Although some of the points are obvious and are in need of some love. I have always thought the way the logout/shutdown functionality works was a bit "clunky". I think it would be nice to lose the tab off the menu and move the functionality to one button which would display a single screen with the various options. From memory (and hows this for a link) I think there is a plasmoid that sits there to do just that!
