Speed.  There was a point at which we were considering moving our
software to Linux from Solaris because clients needed to do a lot of
number-crunching (it's optimization software) and the Solaris machines
were *slow*.  Switching to a 64-bit machine running Linux -- or even a
32-bit machine, because x86 processors are still faster than Solaris
machines.  But then Solaris came out with Solaris 10...

We are still moving our machines from Solaris to Linux, though, but it's
for the "cost" reason -- the hardware is much cheaper.

However, since Solaris 10 does also run x86 machines, I'm not sure but
we'll still be having a mixed Unix-Linux environment.  Linux is
friendlier and nicer for users and admins, but Solaris is still reliable
for servers.

As for the positive rant about HP-UX, yeah, I believe it. I used to work
for HP and the obsessiveness about quality assurance HP had I have never
seen with anyone else I've worked for.
