Corporate didn't run from sole-source hardware then, in fact corporate gravitated towards it. Now you say that's a reason for corporate not to use it, probably just because it has the Apple name, a brand with which you have no experience.
BTW, lock-down is so incredibly easy on a Mac. I set my kid up on mine and the parental controls allowed me to easily control exactly what she can and can't do, down to which applications she can run, what preferences she can change, what sites she can visit, when she can visit, how long she can use the computer, etc., and it's all logged. Sweet. And that's just what's available through the UI on the desktop version.
IBM's microchannel architecture died because corporate wouldn't buy off on sole source hardware on the desktop or for PC servers. In markets where you really don't have much of a choice, like mainframes, they can't really make it a deciding factor, but in the PC market it is and always has been a factor.

Cool. How easy is it when you have 10 of them, scattered over a 300 mile radius?
