I think if you're planning on running a business of OSX machines, you probably shouldn't rely on hackintosh stuff. Upgrading the OS on hackintosh is pretty painful.
Point releases updates on real hardware is so easy. My Hackintosh scares me to even update Safari and the self-updater has managed to brick the computer with just security updates (really stable when not updating tho :)
This is by no means specific to OSX.
