BARCELONA, MOBILE WORLD CONGRESS 2012 — When we stopped by HTC’s booth today, we were impressed enough by HTC’s new line-up of One flagship phones, but what really caught our eye was some of the great stuff they were doing with Android software. HTC’s got a great new music app that unites all of your music whether stored locally or in the cloud; they’ve also got a great new camera app that can take fantastic stills from video. But what we really liked was what HTC was doing in the last mobile frontier, the automobile, with HTC Car.
