Perhaps travel bloggers are already doing this? I thought this is a great way to leave your digital 'footprint' on the map. So, I'm thinking, why doesn't Amazing Race do a special series where participants do a real-time race all over the globe? Guess what, it'd be a great way to place the iPhone in their hands. I know having a phone makes things easier but the rules could be more strict. What a better way to promote Google and Apple together - in case this rumor comes true.
