As predicted, Microsoft used it's Build developer conference to launch Windows Phone 8.1, the latest version of its mobile OS.
Microsoft's Joe Belfiore took the stage and talked up (among other things), new hardware partners like Prestigio and Micromax that should help the company penetrate developing markets.
WP 8.1 comes with a quite a bit to cram into a single update but the most anticipated feature was CORTANA. Your PERSONAL Digital Assistant, just like apple's siri, and google's google now.
according to microsoft "Powered by Bing, Cortana is the only digital assistant that gets to know you, builds a relationship that you can trust, and gets better over time by asking questions based on your behavior and checking in with you before she assumes you’re interested in something. She detects and monitors the stuff you care about, looks out for you throughout the day, and helps filter out the noise so you can focus on what matters to you."
