"My favorite toy growing up was Polly Pocket. But one gift that I wanted though never received for Christmas was a pair of trampoline moon shoes. You strap them to your feet and they have springs on them, and you can just jump around!"
"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."
