Oh yes, which user? :-) We've done the user testing on this. Instant-apply
wins hands down. The traditional "OK, Apply, Undo, Cancel" foo doesn't fly.
You'll see very similar behaviour on Mac OS - just like GNOME, it is almost
entirely instant-apply (sometimes, we have to expose frustrating mechanics
underneath). Rather than dealing with an abstract idea of changing settings
and committing them, you are dealing with the software head on, hands on.

Everything goes through gconfd.

http://www.gnome.org/projects/gconf/ would be a great place to start if you
really want to know what to flame. You should also read the GNOME System
