I would agree with the point of demanding a longer lifespan of gadgets. One problem I see everyone making simply for the amount of money spent now is buying the "old" laptops or competers and replacing them every year, maybe two. Yes, there are times financials are tough so I do understand but others could buy a little better product to last longer.
Also mobile cell phones. Industry is huge and not going away. Contracts are for two years, there are even shorter contracts you can get now so you can replace the "old" phone with a year newer model. I guess I don't have too much room to talk, I have 4 smartphones (all sitting in my backpacks front pocket) from 3 years of having a data plan. It's so ingrained in our society to have the best and newest phone that company's have taken complete advantage and are releasing their new models yearly with technical specs that made little to no difference half the time. Seeing phones last longer than they do now would be a great improvement.
I am very interested in seeing how this all plays out as we should find at least some way to slow down waste.
