While this is true for some most use Macs and there is one huge advantage, Mac server allows remote user files on the network, so as soon as someone gets to work they login to their user account when on the network and all files, programs, and everything load up onto the user machine until they logout or leave the network.
This is done at schools and most larger companies that allow personal Mac laptops, or bringing home of laptops. That and or rotating network logins that when you load up you need to enter employe info before network access is given.
