It was a good session. I totally buy MS's Data Vision.
The most interesting stuff for me is the Entity Framework.
At last there will be a conceptual data model that all MS products will share (Reporting, Replication, Analysis Services, ADO.NET). This is a big and important improvement in the way we used data.
The 'Data Dude' tool looks cool. If they manage to integrate it with the Entity Framework, it would rock.
