Yes, it's official: Microsoft is bringing Windows' Cortana voice assistant to Android and iPhone. Both platforms will get a dedicated app that, much like you see on Windows Phone today, will let you dictate reminders, track flights and otherwise keep your life organized. Cortana's Notebook, which remembers what you like, will also sync across all your platforms. This won't be a one-for-one recreation of what you get right now, though -- since Microsoft can't tap directly into the operating system like it can on Windows devices, you won't get hands-free activation through "hey Cortana" or options to launch apps or settings. Still, it'll be worth seeing what this Halo-inspired helper can do when it reaches Android in late June, and iPhones sometime later this year -- and we'd add that it's not the only treat Microsoft has in store for your smartphone, either.
