It has been rumored that this fall, the Bing iOS app will get Cortana, just a few MONTHS after WP, which doesn't make WP have an advantage over iOS, at least in this reason. It's also been reported that it will even get it before Microsoft's own Xbox One and Windows. Quite annoying if you ask me, what about you guys? Also, don't forget to take the poll!
