Believe it or not: I never worked on an IBM mainframe, except in college. It always seemed like the prejudices against it meant that, once you get into that world, you can't get out. That said: what the business types like is the belief, whether it's true or not, that when you call IBM for service they're there before you hang up the phone. Also, a long time ago at Oracle, I sat in probably the most boring meeting of my life: a group called MOSES, composed of sysadmins for Unix. Their complaint was that, supposedly, all mainframe sysadmins did things the exact same way, so if you hired a new one, there was no training. Whereas in Unix, everyone did things differently, so a new hire couldn't be productive right away.
