InfoWorld: The new enterprise portal: January 09, 2004: By Eric Knorr: Applications "And how does the world's largest software company fit into the portal picture? While most agree that the latest version of Microsoft's SharePoint Portal Server is a good product, the company is clearly ambivalent about enterprise portals. And no wonder, Phifer says. "If the Webtop became a reality, Microsoft has the most to lose because right now Microsoft owns the eyeballs of corporate Earth," he says. "And if I suddenly switch over to a Web browser with a portal being displayed, my eyeballs are focusing on the portal and not on the Microsoft desktop."
This is missing the point -- the Longhorn desktop is the future Microsoft portal client.
