According to Aaron Tan, ZDNet Asia, "Gartner estimates that only half of Microsoft's customers with more than 1,000 desktops worldwide have purchased SA for Microsoft Office or the Windows platform, and only 65 percent of this clientele are renewing the maintenance program."
While Ed Bott argues that a price increase doesnt make sense, especially given the impact on customers with Microsoft Enterprise Agreement and Software Assurance as explained below - they may end up paying double!,
"If the goal is to increase adoption, a [Vista Enterprise] price increase doesn’t seem like the smart way to do it, especially given the bad feelings that a lot of enterprise customers are going to feel having purchased three-year SA licenses for Windows and Office in September 2003 with the assumption that they were buying upgrade rights to Longhorn and Office 12. Oops." in http://blogs.zdnet.com/Bott/?p=104
a recent interview with Microsoft executives - see Joe Wilcox analysis: http://www.microsoftmonitor.com/archives/016739.html - does point to potential price increase!
"By the way, Kevin confirmed that Microsoft would charge more for Windows Vista Ultimate, and presumably Windows Vista Enterprise, than current Windows XP pricing. He described the increase "modest." Maybe, but it's also the first Windows price increase in more than a decade."
So, this also means that customers whose Microsoft Enterprise Agreement is expiring after Vista/MS Office shipping date, have yet another reason NOT to renew their Microsoft Enterprise Agreement!
