All the HP-UX sysadmins I've encountered disagree with you on both points (although 'dominant OSs of choice for <arbitrary undefined group>' can mean just about anything). They generally only use it because either (a) they can't afford a hardware upgrade, or (b) they have some weird proprietary application that won't run on anything else.
When I say "dominant OS of choice" what I mean that in terms of dollars spent on new and existing systems, last year more money was spent on systems that run HP-UX than all Linux systems combined. This is the nature of the big-iron Unix market. 5% of the systems consume over 90% of all dollars spent on Unix-related systems.
You should be happy that these systems bring in big money since they confirm that if Linux stays on its current path, eventually Linux will be the OS of choice on big-iron systems (IBM is a major promoter of this).
I am happy to know that software I support is used on million dollar systems as well as PCs. It is one of the joys of open systems.
