I agree with the other commenters, I don't see much from the query language itself. However, the plotting integration is very interesting for exploratory-type analyses or quickly figuring out what's going on with your data in a pinch, I found myself wishing for something like that on many occasions. As far as the "next SQL" goes, my hunch is that we should learn our lesson from the various ETL tools that became popular in the last two decades and base it on infinitary stream algebras, it seems like it's the correct computational model to deal with generic, potentially non-uniform data. (I'm afraid I don't have the chops to argue the idea further, though --)
