Not much to say, really, apart from the fact that you can now use pivot tables in Google Docs:

Yet another small step closer to Google having something resembling a BI solution… integrate Fusion Tables, Public Data Explorer, BigQuery and this and we’ll have something interesting, although I’m not convinced Google has a coherent BI strategy or thinks it needs one.
cool feature, what-else can we say?
