how far have mac's made it into large installations?

[Ray Wong]

Hi all, found myself wondering:

Seems like Macs have become a lot more common, mostly on the corporate
IT side but I guess a few are using them for internet operations too.
Haven't really been keeping track about what options and resources are
out there for managing them... Been seeing more claims of malware,
intrusions, et al., and wondering if any professionals are actually
dealing with them in some systematic way with useful management and
recovery tools, or is it largely still the same "so and so head of
<some creative and not terribly technical department with lots of
discretionary budget> wanted em so we're living with them" approach?
