I wonder what that pie chart would look like if they polled only tech people. Linux would have a much larger slice of the pie.
This was not a poll, in the sense of “Which OS do you prefer?” If was a Report on the installed Desktop OS, so the janitor could have walked through the building and come up with the same percentages as IT or Marketing or whatever.
Define “tech people”. If you mean “I.T.” (i.e. “Information Technology”) and are asking which is their preferred OS, then perhaps Linux would prevail.
If you mean engineers as “tech people”, then probably not.
BTW, When I first started in I.S. with my former Fortune 500 employer, our division’s computer department was called “I.S.”, “Information Services”. Somewhere along the way they changed it to I.T. By then I was working in Engineering Services and could see that the focus of “I.T.” was no longer on Service to the company as a whole but rather on Information Technology, as in “This is OUR thing and making it easy for us is more important than providing a SERVICE to the rest of the company”.
Inbreeding. Inside the Beltway Syndrome. Loss of perspective as to the purpose of your department. Of course, in many companies, HR (Human Resources) is the worst offender in this regard.
