I've been on XFCE on Debian since KDE 4 came out. Recently I had a fresh install and checked gnome out of curiosity and it turns out I'm too old-fashioned for this.
However, I don't have time to figure out how to "fix" it for my personal needs, and I can't be bothered if it involves more than a single conf file I can save in a gist...and it's certainly not compelling enough to move me back from something as simple as XFCE.
[1] note: I don't use most features in OS X, but the dock and whatever "show me all the desktops" is called, I do heavily, as well as a keystroke launcher.
