Enterprise IT departments seem unconcerned about the loss of WinFS from Longhorn, the next generation file system that was supposed to debut with the new OS. Microsoft has dropped the technology from Longhorn to try to make good on its 2006 release date for the new OS. Quite a disappointment to techies like us, sure. But the business world seems unphased. "I'm not hearing demand from enterprises for WinFS or a unified file system. It's a theoretical benefit that's been hard for Microsoft to explain. This is a pragmatic [step], and overall it will let enterprises and developers do better planning." - David Smith, vice president at market research firm Gartner Inc.
