Other Potential Uses for Cortana

[diplomat696]

So with the discussion about the evolution of Cortana coming hot and heavy it made me wonder could we see Cortana in use in other systems. I guess in a way systems like the automated response lines some of the major banks use are similar in design to Cortana, wouldn't it be interesting to see a personal assistant like Cortana in use when you call somewhere like that instead of the dumb robotic monotone ones generally in use now? Does anyone else have any thoughts on other spots it could be used beneficially?
