One of my favorite things about Google's Street View are the bizarre pictures you can find in it. There's a great one of snorkelers chasing the Google Maps car down a street in Norway.
It is also an incredibly useful tool though, which is not easily accessible on the Maps native app. Comes in Streets, which uses the maps from Apple, and merges it with Google Street View in a very simple layout. It's like Romeo and Juliet but without tragedy at the end! Today it drops from $1.99 to $0.99!
