One of Google's favorite pastimes is shoehorning bits of new functionality into Google Maps for Android, probably because... well, because it can -- updating a package on its own mobile platform is a heck of a lot easier than, say, getting Apple to add a feature to its Maps app. To that end, version 4.3 has just rolled out with three major additions: aggregated (and color-coded) business reviews broken down by topic, transit system departure times, and suggested friends for Latitude. We'll admit, we occasionally forget that Latitude exists, so this seems like a timely addition to get it back into the spotlight -- and if you live in New York, Chicago, or another city with a sprawling bus and subway system, we're sure you'll be amped about the schedules. Now if those times were actually correct, that'd be really mind-blowing.
