Office servers are all running RHEL, except the Oracle database appliance running their Oracle Linux. Office desktop runs Linux Mint and Windows 7. I don't have time to mess around with stuff like Gentoo and Arch any longer. Laptop runs Kali Linux and Windows 7. Media center, wife's laptop, kid's PCs and my gaming machine all run Windows 7. PBX system runs CentOS. Media server runs Ubuntu server. AD and monitoring server runs Windows Server 2008 R2. I only run OS X in a VM, because I don't like Unix made by Fisher Price.
