In a wristwatch imagine the battery is in the strap and there's a medical sensor in there connected to the internet. If someone is monitoring that they could phone up if the user has forgotten to take some medication. This could save hundreds of dollars in medical fees later. What's missing? It's a stable battery.
I want to say with the utmost of sincerity not as a Republican but as an American that I have great respect for Senator Obama's historic achievement to become his party's nominee not because of his color but with indifference to it.
