From Lifehacker today they outline the new Google Maps with turn by turn navigation which will be available on all Android powered phones. This is really cool and should help me find my way quite nicely. If it works as well as shown in the video then it'll be better than the built in GPS in my Wife's vehicle, as long as you stay in a service area for your phone I assume. Hopefully this was thought of when developing it to at least keep giving directions while disconnected by storing the data on your phone somewhere.
