Gee, kind of a defensive bunch, aren't we? I think it's a reasonable question, albeit not the only possible reasonable question one might ask. Hard to believe that if I asked on slash-dot how many Linux shops there were, I would get answers that mostly ran to "it doesn't matter - ask a different question."
Yes, I know that mainframes are generally bigger than PCs and generally do more mission-critical work. I know there are some very small development shops - I do work for one of them. Yes, I know about LPARs and datacenter consolidation. I've heard IBMers at SHARE or an MVS Technical Conference or BP Conference bandy about numbers in a "cute" fashion - you know, throw up a slide for about 5 seconds that's not in the handouts, that sort of thing. Last time I heard a number, it was about 10,000 worldwide. I saw a slide that broke it down by major marketing region. I *think* that may have been in the mid-nineties. Nobody's heard a number since then? Not even one you're willing to share privately? Sheesh!

I know IBM does not generally publish numbers, but does anyone have a good working guess they can share with me on the number of organizations worldwide using Z or 390 boxes? Something to the nearest thousand would be great. Alternatively, I could live with the number of organizations in the US only, or the number of installations (as opposed to organizations). Or OS/390 and z/OS numbers as opposed to box numbers including VM and VSE. It's for a presentation to software people who are not familiar with our box. It's not the point of the presentation -- it's just for a "no, the mainframe is not dead" slide that is a footnote to the presentation's main point, which has nothing to do with choice of platforms.
