Microsoft just made Cortana considerably more useful on smartphones -- provided you're an early adopter. It has announced a version 3.0 beta for Android and iOS that delivers a major interface overhaul with some valuable features. Gone is the blue-laden (and slightly dated) look you see above. Instead, you'll see a more modern-looking (if slightly plain) design with a prominent voice command button. More importantly, the interface now enables "conversational experiences" (that is, a more back-and-forth chat) with Cortana as well as a dedicated place to set up your Cortana-capable devices.
