In response to Google Now and Apple's Siri, Microsoft has announced its own voice-control companion for Windows Phone. Cortana will be available in the release of the next update. I found this interesting being a Windows Phone user and a fan of the Halo series. Cortana appears as Master Chief's A.I. companion in the series and will now be a companion to any windows phone user as well. I think this is really helpful to what the phone can do because right now voice control can only do a limited amount of tasks, such as open an app, make a note, or text someone. With this next update I will be able to perform tasks similar to what Siri can do, as well as feel a heightened sense of joy every time i talk to Cortana. It's like having Super Mario or Thomas the Tank as a personal companion.
