KDE 3.5 is finally out. I've been using Beta 2 for some time now, and I can heartily recommend it. In addition to being serious eye-candy, this is probably the first significantly usable, yet powerful windowing system for Linux.
KDE has always been extremely configurable, and this version does not disappoint. Significant chznges include applets that you can drop onto the taskbar, transparency support that would really rock if X would let it, the Kopete IM client that finallly manages to kick the aweful GAIM in the arse, and a bunch of cool navigation tools in Konqueror, which i prefer over firefox.
I really hope more people use KDE, and bury that text-console simulator for VGA, more popularly known as GNOME.
