As someone currently doing a "pilot" of a Mac in a highly corporate environment, I can say it's not exactly just IT. There's realms and realms of support groups that get to sign off on "authorized" network equipment, and when you bypass them it's the equivalent to a histamine reaction. I never met anyone in IT who disliked Macs completely and totally, just management. We had one specific storage group that "only supported Windows," despite the storage pool being a Samba process on Linux and all of the core devs using Macs (they had shell account access, so never encountered this). The dev who supported the share outright refused to add the "unix extensions = no" to the smb.conf file (that fun bug). Right now I actually run a little CentOS VM to mount the share with the "nounix" option, then SCP in. So, even once you get the platform, it can be a major struggle to have other groups support it.
