Bing Maps is decent, but lacks drill-down features like the handy-dandy public transit directions found in Google Maps. Don’t think that’s a big deal? Witness the uproar over Apple’s switch to an in-house Maps app on the iPhone.
The Windows Store offers two unofficial Google Maps apps, confusingly named G Maps and gMaps. Both apps support the standard Google Maps features, including directions for driving, public transit, walking, and cycling; location search; layers; and satellite maps. Each can also track your location via GPS if your tablet has a GPS chip.
Of the two, G Maps has much smoother transitions while zooming, though it does pester you with ads. Hey, the developer has to make his money before a real Google Maps app appears, right?
