It could be an app where everyone could register by himself his product when it' s bought. Then everyone could register the moment when his product is not more working and it' s not more convenient to fix it. These data could be available for registered user. So, if I want to buy a phone, or computer or a similar device, I can avoid the brands that I can suppose to use "obsolescence programmed", a fraudolent and catastrophical practice from an ecological point of view. Obviously we have to refine this app, managing to avoid the input of fraudolent or not useful data.
