Google Maps had 'em -- schedule a trip on public transit and the app would tell you exactly when the next few trains or buses would arrive (or, at least, were supposed to arrive). But, getting to the full schedules yourself was never possible. Now it is, with Google Maps getting an update to allow you to tap on bus or train stations and retrieve a listing of which lines will pass through and when, making it a little easier to identify a proper last call that won't see you springing for an expensive taxi ride. Beyond that, Google has re-organized the information about restaurants and other businesses, and will also suggest friends who are sharing their whereabouts on Latitude. That last bit is helpful if their last call was a little later than yours and they're now too inebriated to tell you where to find them.
