This is the "what the office uses camp". Interestingly, you like Windows primarily due to the manageable power that it gives you over other people ('s computers). Fixing the user experience at the expense of centralized control would not be an improvement to you (but it probably would be to your users).

BTW, having worked IT I fully agree with you. Mac OS X has a good notion for how one might manage groups of computers (NetInfo), but it isn't as pervasive at the application level and so it isn't as powerful.
