Software vulnerabilities still dog operating systems
http://www.theinquirer.net/?article=13420

"Proprietary systems are the least vulnerable

The operating systems with fewest vulnerabilities in 2003 are HP's
OpenVMS, IBM's OS/400 and IBM's zOS.

These three are all proprietary and they all have security that is
fully integrated, not applied as some kind of after-thought. Certainly
they come with a decent price-tag but they can be well worth the money
when the result is fewer security problems, less unscheduled downtime
and less downtime for patching."
...
"the most secure operating systems continue to be certain proprietary
systems from HP and IBM. Some may refer to these more secure systems
as legacy systems but if legacy means secure and reliable it seems
that legacy should be the preferred option."
