Comment You're forgetting SBS (Score 1) 225
Of course the numbers are inflated by MS! A Sharepoint license comes automatically with SBS and Enterprise versions of 2003 and 2008. I have plenty of customers who are running SBS, and very few of them are actually utilizing the Sharepoint license that they have, nor are they utilizing the Exchange license that comes with it either. In MS's defense, Sharepoint is actually really cool for what it does, but it has a fairly limited target market.
