As the OP, I'm sorta inclined to resent this, but I know I was just whining some. Although I think zBoxes and z/OS plus zLinux are the no brainer way to go, I also recognize I am a pro mainframe bigot. My underlying concern, which I related in a later post is the real point.
We now live in a world (z or Wintel or *nix) where downtime does not have to visibly happen. And customers are permitted to and should insist on 24/7 service. But the other fact is everyone (well almost) has a Window$ workstation on their desk that many reboot every day, and certainly (if updates are properly being applied) doesn't stay up more than a week or two. This leads to the mindset that downtime is acceptable. And maybe it is for many(most) applications. I don't include financial in that group, and I certainly don't include any related to public safety (Police, Fire, etc) in the group.
