I've been very disappointed with Cortana. On numerous occasions it has been faster to grab my Macbook out of my backpack. Why is Spotlight able to find a file on my Windows desktop's network share that Cortana would not find? And to top it off Spotlight shows me accurate previews of Excel and Word documents. But Cortana, another Microsoft product, does not. Perhaps that's a compliment to the team that makes Office for Mac.
