Microsoft Watch - Web Services & Browser - The Most Important Microsoft Release of the Year

Agreed... 

But getting lost a bit in the noise and hype is one Microsoft product release that, in the long run, may end up being the most important, especially on the enterprise side. And that product is Microsoft SharePoint Server 2007.

Listed ostensibly as a component of Office, SharePoint is actually much more. You can make a very good argument that SharePoint is now the core platform on which almost all Microsoft-based web, SOA, BPM, ecommerce, content management, collaboration and of course portal initiatives will be built.
