I left KDE back in the early KDE4 days. I had always been a KDE user
since first using Linux. The other day I was tinkering around and
decided to try KDE on Fedora.
Boy, was I surprised. Not only is it well integrated, it's pretty
much a Vanilla upstream KDE, and at 4.8.x, KDE now rocks again. I mean
it's solid. It performs well, has features that I like and I very
quickly was right at home again. The performance savings of a lighter
desktop like Xfce seem to make more sense on lesser hardware...
