The entire crux of any discussion on Microsoft's behaviors hinges on one figure: What percentage of their Windows and Office revenues are coming from end users versus corporate sales? I mean, I think it's kind of obvious, but yet we still have arguments about why they would screw users with these sorts of decisions. It makes no sense to me. Further, (and deference to Tom Warren), but I would bet that a lot more IT admins are happy with this change than there are those who are angry.
