Interesting, but what about the OS's that matter? (Score 1)

From a revenue perspective, this isn't the list of "2006's flagship operating systems." I'd like to see a survey of the operating systems used to run the businesses that affect my daily life (businesses like banks and credit card companies). This is the realm of z/OS, HP-UX, i5/OS, and AIX. However, I'm sure that these systems are buried so deep behind firewalls, that vulnerability scans don't even make sense.
