For warehousing & reporting, "Add hash for evaluating GROUP BY aggregates" 
can be a killer feature.

A nightly reporting process that starts here at midnight each night
takes about 12 hours on 7.3 and about 9 hours on 7.4alpha; possibly
thanks to HashAggregates.   While this may not sound like much, it 
means Marketing could see results when they arive at work, instead 
of waiting for afternoon.  

The perceived improvement of "ready before work" vs. "wait three hours" 
is a killer feature for this system.
