I like XFCE *as my fallback desktop* when GNOME goes kablooie in unstable/experimental. Tis nice to have somewhere else to run :-)

Primary desktop is GNOME2.2, because it's fab.

X isn't the problem. X is the answer. "What do I use instead of all these half-assed incomplete undeveloped dead alternatives to X?" is the question.

X has one magic property that means that it will be used for years and years. It's good enough.

As I noted elsewhere, the disillusioned comments of one developer of one particular distribution of X doesn't constitute either a policy statement nor a particularly deep insight.
