It is hard to get away from Windows. It has been imprinted on people's
consciousness for generations now.They know that here are other OSes but
could not name them save maybe to mention Mac which is not an OS. When it
comes to servers they transfer their prejudice even though Linux rules when
it comes to servers. They want easy. They are familiar with Windows and
know that they can at least converse a bit with the tech people about it.
The biggest selling points for Linux right now are Red Hat which became a
billion dollar company in 2012, Android which everybody has heard about and
supercomputers where Linux has ruled for a long time. Of the top 500
fastest computers in the world 457 run on Linux, 30 run on Unix, 11 run
mixed OSes, and Windows runs on only 4 and those are sponsored by
Microsoft. This shows its popularity, power and scalability. Many large
companies are Linux shops from Google, Amazon, Wikipedia, eBay on the net
to IBM, Morgan Stanley, Goldman Sachs, Bank of America, Bristol-Myers
Squibb, NTT, Deutsche Bank, DreamWorks, ADP, Bank of New York, NYSE, NASDAQ
QMX, Goodrich, MetLife, Panasonic, Cisco and AIG which are all Fortune 500.
It is estimated that at least 75 per cent of Fortune 500 companies deploy
Linux at least in part.
Two reasons most cited for why organizations select Linux over alternative
server operating systems is cost and technical superiority. The three
recent trends that are further driving the demand of Linux are cloud
computing, virtualization and Big Data.

Good luck trying to change minds. Sometimes they are closed and do not want
to be opened.
