Bill Gates and Steve Ballmer talked a little bit about Windows 7. But just a little bit. Speaking at the All Things D conference, Ballmer, Gates, and Microsoft's Julie Larson-Green demonstrated some of the features that will be included, including support for Surface-like multi-touch technology. A couple of high profile web sites have been claiming they have some new leaked screenshots of the Windows 7 interface. But as blogger Long Zheng points out, it appears that these images were just concept drawings from someone guessing what the new OS might look like.
