Google Maps is awesome. You know why it's awesome? Because of stuff like this. On the Lat Long Blog today, Google announced that it has implemented new 45-degree flyover imagery in 51 cities (such as below) around the world - 37 in the US, 14 abroad.
Satellite imagery has also been updated. 17 cities have refreshed space-based shots, along with 112 various regions in a whole bunch 'o countries. So, today's probably a prime opportunity to go around gloating to those friends of yours who are, shall we say, less geographically fortunate.
Here's the full list of locations with updated data.
