“For the university, home hacker and large, well-established
Unix shop, multiple versions of Linux and other Unix systems may be
very acceptable. But most companies do not want to know or have to
care about what operating system is running their applications.
They certainly do not want to have to find and retain very
expensive folks to install, maintain and enhance the OS. They want
it to run out of the box without having to search the internet for
a driver that actually works. The most significant problem with
Linux is not any technical weakness. The biggest problem is that it
is yet another operating system to be supported by application

“The benefits of Linux stem from its development model.Linux was
created–and is continuously updated–by a community of the world’s
most skilled programmers. Linux is free not only in cost but also
in the sense that it offers access to the source code. This
presents businesses with the tremendous flexibility to shape their
information technology structures without relying on the whims of a
vendor. Moreover, because Linux is constantly improving, users
don’t have to wait several years for the next version. With
proprietary operating systems, you could wait months for a bug
patch if the vendor ever decided to release one. With Linux,
updates and fixes are continually available, and you don’t even
need to bring your systems down to apply them.”
