With the new version, you'll be able to do most of what you can do now. You can't use it for navigation and other tasks we've come to expect in digital maps. It lets you save a small region ahead of time, but it's the equivalent of displaying a paper map in a phone app. Google Maps has had a limited offline feature. Offline mapping is also available with some third-party apps, including Nokia's Here. Mapping apps included with Windows phones have long had this feature, but Windows has a tiny market share compared with iPhones and Android. Google is also targeting users in emerging markets, where cellular speeds are slower and prices are higher relative to typical incomes. It's also great if you're travelling abroad and want to conserve on expensive data plans. The feature is ideal if you're trying to leave an underground parking garage or a remote national park. Google says a version for iPhones will come soon. With an update for Android phones Tuesday, you'll be able to search nearby businesses and get driving directions, including turn-by-turn voice prompts, even if your Internet connection is spotty or non-existent.
