Google Maps

Google maps are slightly better than other online map services. I’m waiting for them to layer Keyhole images over the maps so the user can see a birds-eye view. Mapquest used to have an option to view satellite images, but Keyhole has done a much better job.
It’s interesting that Google doesn’t point to their map service when you type an address into the standard search box. They recognize the address and instead point to Yahoo or Map Quest.
