My colleague Steve Arnold recently blogged in these pages about how recent delays in Windows Vista and Office 2007 will impact the search marketplace, while other commentators have examined implications for the IT market at large. However, little has been written on the impact for the existing and potential users of Microsoft CMS and Sharepoint. For those customers, delays mean that more code and content will get deployed on the old platform, which translates into a bigger migration effort next year. So, what might be good news for competing vendors is really expensive news for Microsoft's customer base...[Update, 03 April: To clarify: So far it is only the consumer editions, and not the volume-license business editions, that are delayed]
