Andrea Barker (abarker15@msn.com) is back to show us a bit of Cortana - which is, weirdly enough, Microsoft's virtual assistant speaking through the A-lady. Perhaps Cortana is going for the 'Halo' effect by appearing through the much more amazing Alexa (sorry - that was a really bad pun on the fact that Cortana was originally a character in the video game of that name. You knew? Apologies.)
