An interesting question to have added to the survey would have been something like.
What portion of your training was focused on Microsoft operating systems?
25%, 50%, 75% 100%
or something that solicited information about the respondents non-microsoft experience.
In my experience when the IT department is asked to look at an OS other than Microsoft they become very flustered because they don’t usually understand any else or if the senior staff do, they fear they won’t be able to find support staff that does.
Microsoft is more of a marketing success story than a technology success story.
