Why use a todo app that requires me to grab my phone, unlock, start an app and enter a todo item, when I could instead just press a button that'll be right in front of me at the moment I notice I'll need more of some product soon?
> It's taken me 2 weeks so far to remember to get it. I go to the store almost daily. :(
This is a behavior that isn't going to change by having a thousand buttons all over your house. Maybe you won't ever worry about running out of detergent or dogfood again, but there's always something else. "Oh shit, I bought pasta for dinner but I forgot to buy pasta sauce!" What's the solution, get a pasta sauce button?
I see nothing wrong with dedicating a wall of my kitchen entirely to Amazon buttons for everything in my fridge and pantry. :)
As I mentioned in another comment, though, a better system would probably be to use some cheap, single-purpose wall-mountable tablet computer (probably e-Ink based, maybe even with a column of physical buttons instead of a touchscreen to bring costs down to a pittance) that one could load up with a list of products that need to be routinely reordered for a partiuclar room. If prices could be brought down considerably (if not free with Prime membership, as is being proposed for these Dash buttons), this could be pretty viable.
