+1 I don't think there is a proposition as powerful as the entire Microsoft ecosystem on the business desktop.
There is also support, training, excellent literature and documentation, large quantities of staff, functional software at a reasonable price and as you mention: Active directory (which is awesome if you actually understand it).
If you've seen some of the shit I've seen wired up to Office in the last few years, you'll get it. It's just awesome. Entire businesses hang of it. It might not be clean and squeaky but it's functional and does the job. Google Docs + iWork + LibreOffice are precisely zero competition.
(I have to add this to each of these posts to avoid the shill downvotes: I am primarily a Linux user which suits me but I don't think it'd suit most people).
