Windows Versus Linux Security

Linux and Windows have been competing for a bigger market share ever since and on checking on volume outlet stores such as Walmart and Bestbuy you realize that Windows have a bigger share from the way the retailers are merchandising. Mainstream consumers are known to use Windows alot whereas geeks and industry users prefer Linux especially on the server end.

I would therefore like to know your views on Security between the two OS. Why do Clients prefer Windows to Linux? Is it secure than Linux? and Why do Industry users prefer Servers running on Linux? :rolleyes:
