It's a great way to expose yourself as not knowing literally anything about how enterprise computing works. Oh really, Microsoft isn't going to dominate the corporate space in 10 years? So what's this hot new technology that's going to replace Active Directory, group policies, etc? Sure, a lot of software has been shifting towards platform agnostic and web apps, but as far as providing your employees with computers to work on, keeping them safe from malware, preventing employees from doing certain things on those computers, controlling who can access what...there is only one operating system that is the clear winner here. Not to mention the entire UNIX security model is severely limited. Being limited to 3 permissions for 3 different classes of users is not going to meet the demands of middle management people who obsess over what permissions they are willing to give employees.
