Blowtorch has it right. It is mostly about support for the OS/hardware.

There are other factors that would affect the decision to go for one or another, but whatever those are, not many businesses will decide to adopt an unsupported OS, mainly because:
a) cost of maintenance - It is much cheaper to contract outside support than have in-house developers, and
b) accountability/time to resolve - Debian may be a better distribution than Fedora (IMHO), but if you have an issue with Debian, you'd email Ian and Deb and maybe they'd respond... or not... while with Red Hat, you'd maybe have a 2hr response support contract and have someone work on your issue right away.

There are yet other situations, like it is the case of SPARC/Solaris, where you go with the hardware for your particular need, and take whatever OS comes with it. If you need uptimes of 1000 days+ in extreme conditions (i.e., high heat, dust) , you are not going with Dell/Windows, that's for sure.

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.

       See attributes(5) for descriptions of the following attributes:
