Nomaan,
it is the speed. My first contact with in-memory solution was in Business Intelligence waters - when I worked with a BI tool QlikView. Contrary to what I was used to, QV stored everything (dimensions, measures, calculations) in computer memory. When such a tool need to get some information, it will get it from memory which is way faster then to get that information from the database via SQL query.
But, as it is always, there is other side of coin - such solutions require a lot of server RAM so I don't think it is cheap to have them in large organizations.
