As far as I know, those not flying are out in the desert. I don't know how many World got (at least two?), and whether any more of them got converted to freighters and sent to other operators. I saw an airliners.net pic of one sitting at, of all places, Montreal in '04, with the Delta name and logos stripped off but still with the Delta intermediate-color striping on it.
I'm not sure about Swiss, Thai I think is still flying them, and maybe KLM? I'm not sure if KLM retired theirs or not.
Too bad about the -11, really, but at least it's found a bit of a niche hauling cargo.

I think all of them are flying, mostly cargo. Thai has a few, and EVA has a few as well.
I only flew it once, from LA to Zurich, center seat, we pushed back, and had a 4 hour mechanical where we all had to stay on the plane.
Loads of fun.
