We've all got places to be. Sometimes, though, we just need a quicker, easier way to get there. So if you need to hail a cab, just remember: There's a new gesture in town. With ride-sharing apps from the likes of Uber and quick access to public transportation schedules and fees, you'll never be more than a tap on the wrist away from work or play. And if you're close enough to walk, easy map-routing will get you there quicker than ever.
