Yeah, Google Maps is normally pretty updated in the US. Be wary of the mobile program, though. My dad's program says we can't turn left at a street down the road from our house, when clearly we can.
I love Google's new street view, it's the only thing I use google maps for. Everything else, I use Live maps from Microsoft. Far more updated and easier to use in my opinion.
It's too bad that my country doesn't have street view on google map.
Anyway, i like google map, because when i need to go to somewhere else, i prefer to look at google map than local map.
