We have been very frustrated with the HP-UX 11 support. We have also found
3rd party support for HP (such as Oracle, etc.) to be very poor over the
past few years.
Our HP-UX gods have also been very frustrated as they percieve HP is more
interested in NT support than Unix. I can't comment on that, because
they've been the ones dealing with HP support. We have raised these issues
with HP numerous times. The end result is that we have moved to Solaris.
HP has pretty muched packed up their Unix bag here in town and left. The
only real wins are going to IBM and Sun.
