Not great for precision door-to-door navigation, though it's often sufficient for many people.
To be honest, I found my phone to be more accurate than my GPS. Additionally (importantly) it seems to work even in garages, under tree-lined streets, and in the city where my Garamin had problems picking up the signal. Lastly, it allowed me better accuracy with destinations. Keeping my PS up to date was just too costly and much of a challenge. And when I need to, I can switch to satellite view or even go look at another map using another application without loosing my directions.
