That was until we tried to use it with one of our new machines, a 21.5″, Late 2013 machine. This has been working well, coupled with my BootCamp auto installer means the process is near enough fully automated and used the same version of Boot Camp support software across all our hardware. We run a lot of our Macs with a dual boot setup pushed out with DeployStudio so the machines can double up as standard Windows desktops.
