I want a service that can do the following: Integrate with my credit card ( ala Mint.com ) and do things like this:
For each charge on the statement, geo-locate the business and put it on the map.
For a given time period, put all those charges and locations on a map. Add some cool arrows to show the sequence, and if you threw in the approximate miles per hour that would be awesome too.
Finally, I also want to be able to view my charges on a calendar ( ala Google Calendar )
