If someone came up with a way of doing large scale fleet management of Mac devices (software installs, updates, rights management et al) in a vaugley similar way to the way Windows env (eg point and click) they'd make an absolutely fortune.
Also, if you have system administrators for OS X machines who need a point-and-click interface for everything, you need to take another look at your hiring practices.
Edit: oh and for the initial imaging you need to use NetInstall and System Image Utility, but they're not separate products still.
I would imagine even the new mac pro's can even be rack mounted if necessary.
