I second everything said in this post - and will include that I've had less issues with a fleet of MacProBooks and towers, than with the 50 or so Win machines, all sharing the same domain. Mac simply works, no matter if the domain is controlled by Mac or Win - and in "split" environments with both OS's working in tandem, I've seen none of the issues as described in this article. If anything, the possibility to have Win and Mac share the same domain and NOT use Exchange is more attractive to many uses looking for an alternative and not the behemoth that Exchange can often be.

Kudos to MAC - well done, yet again -
