What is Sony doing?

Go watch this video on GPrime called Sony Revolution.  Looks to me like a table or wall-mounted, self-powered, Internet-connected workspace with individual “widget tiles” that serve different functions when they come in contact with the workspace.  Additionally, the whole system seem to be touch sensitive and reactive to different type of styli (pretty sure that’s the plural of stylus).  If this thing come to be and is affordable, it truly will be a revolution.
