This thread is not just about Dash button, but anything that we would consider awesome/fantastic 10-20 years ago, but no seem creepy/odd or make us ask why?
I actually think it is a good idea, because it hits how people use consumables like that. You go to watch some clothes, realize you’re almost out of detergent, then remind yourself to order (or add it to your list to buy at the store) some more. Then you get on with what you were doing, and then forget to order and it happens again. Not until you run out or you remember, do you get what you need.
People get around this by just having it be apart of their regular shopping, but that isn’t always the case.
These buttons would fit in that niche of needing more soon, and not having to do anything more than press a button. It isn’t meant to save time, but add convenience and immediate action.
From that article, and my own thoughts on it, I think this is their way to get the data they need to automate these types of things. You first install the button, start using it, then you don’t need it anymore because it knows when you will need it. That or as said in the article, the appliances and things that consume the products would order it for you.
