Hi,
A KDE 4 review from me.
http://www.redhatmagazine.com/2008/05/14/fedora-9-and-the-road-to-kde4/
"KDE 4 shows exciting potential but still has a long way to go. Those who remember the days of KDE or GNOME 2.0 won’t be disappointed at the current state. Today’s new audience might have different expectations, and it is unlikely the majority has the patience to deal with a major rewrite like this one. Even the Linux kernel has moved towards incremental progress over major rewrites in a development branch. The KDE project has taken a big risk, hoping to jump-start innovation. I hope they get it right. Along with the interesting acquisition of Trolltech by Nokia, the future is exciting and uncertain… and that’s just the way I like it."
