There certainly are use-cases for this device. The one I'm intimately familiar with is in smart-metering with gas-meters. These things a battery powered and need to last for ~20 years on that battery. Simultaneously, they're dealing with financial data and communication, therefore all communications are encrypted & authenticated. This device, although may be expensive tho... when you're dealing with 10's of millions of units, that cost really counts. Hopefully someone (ARM) will snap start embedding this type of device within the Cortex-M range... (yes, I know, there already is crypto-acceleration, but more is better).
