Anyone played around with this feature yet? My Google Maps just updated with this being the only new feature. If it actually works, this could be huge - because the big drawback to using gmaps to navigate is that you need to be online to actually navigate (impossible with Wifi only tablets).
I hate the idea of having to use other apps to navigate with because they are all almost always much more expensive than using (free) google maps, have much worse interface, lack in features, etc. Google maps is the best "map" app by far IMO (sans some buggyness it occasionally shows), but it sucks that you can't actually use the GPS features in your TF to navigate with it due to Maps requring internet access in order to navigate. But now, we can! maybe.
