Especially in those cases where you need the extra power provided by UNIX, using Linux to replace NT as a file an print server to NT workstation actually reduces the administration costs because of the similarities between Linux and the various UNIX dialects. In general, there are fewer compatibility problems between UNIX variants than between Windows NT and any other operating system. Because it is similar to UNIX, Linux is an outdated, cryptic, command-line based operating system. This myth is based on a misconception about UNIX, in general. Although UNIX does provide extremely powerful command line tools, there is a wide range of choices of which GUI to use.
People are different and therefore work differently.
With Windows NT, the GUI forces you to work in just one way. With all of the choices of GUIs in Linux, you can work the way you want. Looking at the graphic installation and administration tools provided by such distributions as SuSe and Corel you can see that the statements are blatantly untrue. Most Linux opponents are usually comparing current Microsoft products to Linux products that are several years old. While it is true that are more shrink-wrapped applications for Windows as there are for Linux, there are thousands of applications for Linux that are provided under the GNU Public License, as well as other licenses making them essentially free.
