Apple's iPhone has Siri and Android has Google Now, but it looks like Microsoft is developing its own counterpart: a virtual assistant based on the Halocharacter "Cort
ana." In fact, "she has the potential to be a star for Microsoft," said analyst Rob Enderle. "Xbox is Microsoft's strongest platform and Halo is the strongest brand, with Cortana being the cutest character."
For players of Microsoft's Halo video game series, the computer AI character known as "Cortana" can do much more than just provide directions and plot advances in the game. Soon, however, Cortana could become part of Windows Phone users' real lives as well.
