Where the coverage is (only in the US, but starting to get a lot of cities), the resolution is really good. That shot from Los Angeles was 0.3 meters (per pixel). Some of the data is at 0.15 meters. Geocover 2000, on the other hand, which covers the entire globe, is 14.25 meters. So outside the US most of the public domain imagery is not very good (I think, please prove me wrong!).
Depends on who you get your data from. US goverment is not the only source. While most mondern ones are not going to be PD there are a few historic ones around.
