Yeah my old music teacher has to have a Mac because he has to run Digital Performer, if you write tv and movie music for a living you have to be on a Mac with Digital Performer, its industry stadard. For developers it still makes more sense to have a Mac as well because you can write for ios/android and the web all on the same system. But if you work for an early stage startup like me you probably have a chromeos device like I do rather than a Mac unless you're an investor rather than an employee.
