Why people are not satisfied with FreeBSD?

[Denis Troshin]

Hi!

Looking  at  the  field MAILER of e-mails' headers, I see that there a
lot  of  people here who are using mail programs like Outlook, Eudora,
Mozilla    for   win32. This means that they run windows systems.   So
I'm  asking why still a lot of people here who hadn't move to FreeBSD?

Are  there  any  common  reasons  of why people are not satisfied with
FreeBSD? Why do they still prefer windows?
