While some folks might like disposable products since they "upgrade" so often, I am not in that market and I tend to keep items for a long time. I suspect in most modern phones the part most likely to fail due to heavy usage will be the battery because Lithium Polymers wear out with use. However in my Samsung Note 3, the battery is replaceable so that's less of a concern for me. I'll likely keep using my phone until it can't play youtube anymore. I'm still using a Vaio Z laptop made 5 years ago. It was state of the art in its time so surprisingly it still seems like a fairly modern laptop. It can't run as long on battery and the discrete switch-able graphics are a bit weak but thanks to impressive design, weight wise and size is a match to modern thinish laptop. CPU power is pretty decent too as an i7. So no, I do not like disposable items.
