At the Gartner Symposium/ITxpo in Orlando, Fla., Microsoft CEO Steve Ballmer revealed that Windows 7 is going to be a major release, not just a Vista update. He says the new Windows will have a better user interface, information management tools, and performance. It isn't practical to wait for Windows 7 instead of deploying Vista, he says, since both systems are compatible. Interviewers: Neil MacDonald and David Mitchell Smith of Gartner.
