Voice Search integrated with e-commerce could be the killer feature. Imagine saying "OK Amazon buy those shoes" that are currently displayed on your TV. One or two more steps to confirm the transaction orally and it's on its way. You've already got Prime and you trust that you'll get a competitive price from Amazon. So why not just buy right away?
That's a really great idea. Sadly I can see it being dangerous when the cat sits on the remote and my wife says "I would love to buy these shoes" and we get an Amazon box turn up.
