I hate using my phone while snowboarding. Between the cold and the often lack of service the battery sinks like a stone on the slopes to the point where I have to use it sparingly or risk losing communication with other people on the mountain. So risky to pull the phone out on lift too. I've known people who dropped it there and then it's gone forever. Pinch and zoom would suck in the cold too. I'll take the free trailmap I can unfold with my mittons on any day.
