If you’ve tried out Google Earth or any of the sattelite maps the various search engine provides, then you might like to have a look at http://www.flashearth.com/
It allows you to select the source for the images. Zoom in to your own neighbourhood then flick from Google to MSN to Yahoo (and others) to see which one is the most up to date. (Google by about 3 years, for me!)
