I would strongly second the call for a Discover version of the Excel client. When I build segmented reports and breakdowns in Discover I have to painfully copy paste or email one report at a time to myself to get it into excel. I would like to be able to build what I want in Discover with whatever ...
I agree with 'metricsman' in fact I would go further echoing Adam's point and restate that given the price of Discover we should get some additional, more advanced, pathing reports and visualisations!
