FORTUNE -- Despite a recent management reorganization at Google (GOOG), Marissa Mayer, now vice president of Maps and Local, says it's business of usual, describing the company atmosphere as "optimistic." At TechCrunch Disrupt in New York City, Mayer focused on the progress of her division, and while the basic theme of her discussion was something we've seen coming for a while now -- the tide is shifting from desktop to mobile -- she gave the audience the numbers to back it up.
Users of Google Maps, which just recently surpassed 200 million mobile device installations, now use the service 40% of the time through their smartphones, a percentage that climbs on the weekends, presumably when people are trying to find the apple orchard, national park or backyard BBQ they are heading out to visit. And come this June, Mayer said, the ratio of desktop to mobile usage will flip: the majority of users will use Maps most of the time on their phones instead. Mayer welcomes the change.
