Addictive!

Serious and fun.

On the downside, the "natural language" input works well, though often needs perserverance to get the exact question right -- often less wording gives better results - be sure to keep trying! App could be better if the results allowed point and click on all returned information, rather than just some further suggestions. Also a back button would be nice rather than having to use history tab; allowing hiding the left pane to allow more data to fit in the results would fit the tablet culture.

Still these are nit-picks. This is an awesome app. It does for information what google does for data.
