I remember the days when I used to work contract and at the end of my interview they ask me if I have any questions for them. My questions were always the same:

Will I at any point have to use windows?

Do any of my co-workers in IT choose to use windows on their work laptop?

If the answer to either of these were yes I'd always refuse the job.

Luckily now a days employers got the hint and usually go out of their way not to expose their programmers to windows.
