The Amazon Dash Button @AMAZON is a Wi-Fi connected device that reorders your favorite product with the press of a button. That it exists is proof that the iPhone with an app doesn’t solve everything.
And that convenience can become very, very specific, and also exceptionally wasteful of resources (how many millions of these things and their batteries will end up in landfills?). But I use hardly any of these consumer products, so what do I know.
Personally I think it’s going to be a very uncomfortable two days.
