Integration problems?
Unless the Big Data Appliance comes pre-integrated with their Exadata platform, I don't see this helping "unlock efficiencies, simplify management and create data insights that maximize business value." At least with the example given. Instead we have another isolated data warehouse. Furthermore, having looked at the various Oracle "solution's" you can do better with the right people. Even if you do buy Oracle, you'll still need the people. At best, Oracle will save you some time at a rather high cost and I still have reservations about the time element. You simply can not buy expertise in the form of hardware and software when it comes to analytics (a field I started working professionally at the tender age of 14).
BTW, your insurance example will suffer from all the usual data-cleansing issues that are faced in the unstructured world. The identified social graph from the data collection, ETL, and integration process may, or may not, be accurate. Given the "the state of the art", I'd lay a bet that someone is going to litigate in the not to distant future around this. One need only look at the TSA's "Do Not Fly" list to see an egregious example. At least that investment in more big iron will make the discovery process easier and faster!
