Okay, I don't really know how many chances I've given GNOME, but I've tried to switch to GNOME as my default desktop many times. I always ended up switching back to KDE (to be fair, I use other window managers, too, such as Fluxbox, which is one of my favorites). Thanks to the rumors that Xgl/Compiz/cgwd worked best on GNOME, I gave GNOME another shot. As it turns out, the rumors are false. These 3D desktop enhancements work fine under KDE. But I've really been enjoying my GNOME experience despite the fact that there are still things about GNOME that I dislike. Granted, I can credit Ubuntu's default settings for GNOME as some reasons why I'm enjoying it more. But it's still a better desktop than I recall from the last time I used it.
