Microsoft's forthcoming Cortana assistant is set to arrive in Windows Phone 8.1 and here's a video of it showing off the new Siri-clone in action. And you know what? It is not too shabby.

The video shows how Cortna is truly a personal personal assistant. She will ask about your interests, tastes and preferences. Like a Samantha, but not so sexy sounding. Cortana does indeed look like it is a combination of both Siri and Google Now.

The demo video doesn't show Cortana actually doing anything, though this is as nice a glimpse we can get right now. [Verge]
