Google Maps became my standard mapping program the first time I tried it out. The new map service from Amazon’s A9 is a worthy competitor, however, thanks to its block-level photographs. Type in an address in a major city and it instantly calls up photos of the street taken from the window of a cruising SUV. Walk a block virtually, note relevant landmarks before you drive, or spot someone you know (I found one regular in the Murky Coffee photo).
Wired has more.
